BBC Sport at Wimbledon
Michaella Krajicek's opponents beware: the Dutch teenager clearly has nerves of steel.
Krajicek is through to her first Grand Slam quarter-final
The other day, Krajicek was persuaded by doubles partner Agnieszka Radwanska to watch horror film Hostel: Part II at the cinema.
"It wasn't my choice," she tells BBC Sport, laughing.
"I'm not proud of it and I wouldn't choose it. It's disgusting! After I saw the first one, I promised myself I wouldn't watch another one like that, and then I go and see the second one..."
Krajicek won't have a lot of time for questionable film choices now she has got to the quarter-finals of a Grand Slam for the first time.
The 18-year-old, who is due to face Marion Bartoli on Wednesday, is also competing in the ladies doubles with fellow teenager Radwanska and the mixed with Martin Damm.
"Honestly, I didn't expect to get so far in the singles so that's why I entered both doubles!" says the world number 45, a former junior US Open champion.
"But I'm not that tired yet. I'm not practising so much now - just a hit in the morning then playing doubles."
I'm very proud of having a brother who won this tournament
Krajicek may not be used to going deep into singles tournaments, but her famous surname means she is already adept at handling the press.
Since she made her bow at Wimbledon in the junior tournament in 2003, Krajicek has been quizzed time and again about her half-brother Richard, the 1996 champion.
Does she ever get bored of it?
"Definitely not. I'm very proud of having a brother who won this tournament," she says defiantly.
"It's 11 years ago now that he won and no one has forgotten and I don't think anyone will - I like that. It's better than no one talking about it.
"He's just arrived here and he's going to play in the seniors and hopefully he'll be there to watch my quarter-final."
But Richard, who will play in the invitational doubles with Pat Cash, leaves the coaching to Michaella's dad Petr.
"My brother sometimes gives me advice - but mainly about off-court stuff," says the teenager.
Krajicek's Wimbledon run has taken her past Tzipora Obziler, Katie O'Brien and Laura Granville - but her win over eighth seed Anna Chakvetadze was the highlight.
"That was something really special because I've wanted to beat her since she beat me in the juniors," says the teenager.
"Even though that was about four years ago, I still remember it!
"I really love playing on the grass. It suits my game because I love to serve and just to play aggressively."
Sounds very much like another Krajicek - who, let's remember, had to overcome a series of rain delays in 1996 to win his only Grand Slam title.
