Full-time: Impressive from the Boks. At times encouraging, at times ugly from Samoa. England will have noticed that if they can weather the Samoan storm and keep a professional head they can win. But they'll also have realised that Friday's clash with the Boks is going to be even harder than they first thought.
83 mins: TRY South Africa 59-7 Samoa
JP Pietersen runs in a clincher for the Boks in the right corner. These boys are good.
80 mins: Bryan Habana runs in for a World Cup-equalling record fifth try in a match but is called back for a forward pass.
76 mins: TRY South Africa 52-7 Samoa
Bryan Habana glides down the left wing for a fourth try and South Africa will be well pleased with their afternoon's work. It may not be the dazzling scoreline of the Kiws or Aussies but Samoa are a real physical force and require grinding down.
70 mins: The Samoans seem to be venting their frustrations by sticking in a few more piledriver tackles with just a shoulder, and no arms wrapping around, a la Brian Lima. That's naughty. Stop it.
68 mins: "Os du Randt is clearly still a cult figure with the Boks fans. He got a rousing reception when he went off, the chants of "Os! Os! Os!" ringing in his ears.
"The Samoans look out on their feet now and this match has shades of their meeting at the last World Cup, when they conceded 60 points. The Boks look capable of racking up something similar in the last quarter. "

65 mins: TRY South Africa 47-7 Samoa
After a bit of a lull, South Africa get a penalty and Bryan Habana races forward to take a quick tap to scamper over. Referee Paul Honiss is not convinced he got it down and goes upstairs. But the video ref says it's OK and Percy Montgomery steps up to slot the conversion.
63 mins: The Chiropractor puts in a monster hit - fairly illegally, it has to be said - in midfield but he stays down. He is helped to his feet and goes off in a daze. Meanwhile, the ball reached Bryan Habana but this time Samoa are able to bundle him into touch.
60 mins: Samoa bring on veteran wing/centre Brian Lima - "The Chiropractor" - who becomes the first man to play in five World Cups, stretching back to 1991.
55 mins: TRY South Africa 40-7 Samoa
Springbok wing Bryan Habana wriggles through a small gap and then flicks on the afterburners to score unopposed, giving us the first real glimpse at this tournament of his searing pace.
52 mins: TRY South Africa 33-7 Samoa
The Boks create a big overlap with some good handling going left and Percy Montgomery finishes it off.
50 mins: The Boks squeeze again and Samoa are under serious pressure, but, this time at least, Gavin Williams is able to clear his lines.
48 mins: South Africa are beginning to do what Australia did - and England didn't - easing through the gears in the second half. They cross again but fortunately for Samoa, they are pulled back by referee Paul Honiss.
46 mins: TRY South Africa 28-7 Samoa
One of the easiest tries you'll see. Springbok centre Jaque Fourie hits the line at an angle and races past Alesana Tuilagi to score.
45 mins: The Boks win the line-out and newcomer Francois Steyn breaks out and chips on, finding touch in the Samoan half.
43 mins: South Africa's Jean de Villiers walks off with an apparent arm injury and Francois Steyn comes on. Meanwhile, Samoa have the put-in at a scrum in front of the Bok posts. To the neutrals' dismay, South Africa clear but Samoa pump it back down there and Percy Montgomery's clearance gives the Blues a close-range line-out.
42 mins: Samoa skipper Semo Setiti takes a clever inside ball from Alesana Tuilagi and chips ahead, failing narrowly to gather and crash over. The ball is recyled and Samoa's Iosefa Fekori burrows through to touch down but the referee rules there was an offside.
41mins: Let's get ready to rrrrrrrumble! Samoa kick-off the second half hoping to claw their back. If you're of a queasy disposition you might want to look away now. It's going to be rough and tough.
"There's no doubt who the neutrals in the crowd are supporting. Every time the Samoans have had the ball, the chants of "All-ez les Bleus!" have been ringing round the Parc. It was jumping there for a while after they scored, but a bit more muted now after that second South African try."

40 mins: TRY South Africa 21-7 Samoa
The Boks try to shove Samoa over from the five-yard scrum but after numerous re-sets and a couple of penalties, the ball is whipped right and Percy Montgomery hits the line to thunder over. Montgomery converts.
36 mins: The Boks are bossing the line-out and wing JP Pietersen is almost driven over, only for Samoa to hold it up on the line. There's blue bodies all over the place. I wonder how much they've got left in the tank for the second half?
35 mins: South Africa turn it over in a promising position just outside Samoa's 22 but they rather waste their opportunity.
31 mins: TRY South Africa 14-7 Samoa
Samoan Henry Tuilagi runs right over the top of South African pin-up boy Schalk Burger. Moments later, though, South Africa pour forward and Bryan Habana conjures up a wonderful individual try involving pace and sleight of hands. Percy Montgomery misses with his conversion.
29 mins: The passing down the Bok back line is not good and Jean de Villiers sends an awful ball behind three men.
"SA look as inept as England - if not more so. Samoa obviously the big danger in the group. COME ON SAMOA...!!!!!!"

26 mins: Great running from the Samoa down the left flank. Alesana Tuilagi makes a lot of yards and his brother Henry is also involved but South Africa snaffle the ball, pump it forward and set up a foot race between Bryan Habana and Lome Faatau. The Samaon gets there first but the Boks don't let him up and Samoa get a penalty. Back up the pitch there are fights all over the shop. It's not for the faint-hearted, this one.
24 mins: The Boks spread the ball as far as outside centre Jaque Fourie but the move is a bit laboured and Samoa turn it over and break free.
22 mins: South Africa attack and Butch James kicks on but Samoan full-back David Lemi gathers, spins and launches a counter. The blue shirts are clear but there is a knock-on, another scrap kicks off and they're called back.
20 mins: Wrestling on the floor - or fighting as we could call it - breaks out as South Africa look a tiny bit rattled.
17 mins: TRY South Africa 9-7 Samoa
Sensational. Just as I was banging on about muscle, Samoa created a perfect gap for centre Gavin Williams to sneak through the green line and score under the posts. The Springbok defence was pulled in a couple of different directions and it was easy for Williams. Take note Pool A.
16 mins: For England fans watching, Samoa's breakdown work isn't as efficient as the big southern hemsiphere sides, but the physicality of their open play runners will pose a real problem for opposition not prepared to commit to a tackle.
14 mins: PENALTY South Africa 9-0 Samoa
More Springbok pressure at the breakdown yields another penalty just inside the Samoa half and Percy Montgomery wallops it over.
13 mins: Some good, flat Samoan defence nails Springbok stand-off Butch James in midfield and the Pacific islanders clear their lines.
10 mins: Springbok flanker Schalk Burger is in trouble after jumping for a ball and accidentally almost removing the head of Junior Poluleuligaga. There may have been a punch thrown afterwards but the upshot is Samoa receive a penalty. But Gavin Williams just drags his left-footed effort wide of the right stick.
9 mins: PENALTY South Africa 6-0 Samoa
A bit more biffo as South Africa get a penalty from a Samoan coming in from the side of a ruck. Percy Montgomery slots the points.
8 mins: The Boks are intent on draining the forward strength from Samoa and rumble forward just inside their opposition half before spreading the ball right. Butch James chips through but the ball finds touch.
5 mins: South Africa boom the ball down field and get a line-out in the right near the halfway line. The blonde-haired Schalk Burger tidies up but the Boks crab back inside and play is delayed while Samoa's Henry Tuilagi receives treatment to a facial cut.
3 mins: A bit of boxing breaks out as Samoa try to build a platform from a maul in midfield.
2 mins: PENALTY South Africa 3-0 Samoa
The Boks should have scored there but make a bit of a mess of things, though the left-footed Percy Montgomery comes away with three points.
Kick-off: Butch James kicks off for the Boks and Leicester's Alesana Tuilagi runs it back into a green wall. South Africa get an attacking scrum and surge to within yards of the Samoan line.
1458: Hold onto you hats, gang. This could be a bruising old encounter, Neither of these two are known for taking a step backwards. Boof. After the anthems, the Samoans perform their war dance. I'm all for this stuff - and seeing a haka done in the flesh is a hair-raising experience - but I can't help thinking it hands them a bit of a psychcological edge going into the kick-off.
1450: Sunday's second of four matches is set to kick-off at the Parc des Princes in Paris in 10 minutes.
South Africa will be looking to stamp their authority on pool A after England's limp 28-10 victory over USA on Saturday. This match will lay down the marker, with England taking on the Springboks on Friday in what many thought would be the group decider.
Now, maybe the likes of Samoa have a chance of a knock-out place instead.
