Simon Pegg and Nick Frost are going to star in another film together.
The pair have already had massive hits with Shaun of the Dead and Hot Fuzz, and are now working on a new project called Paul.
Simon told Newsbeat: "It's a road movie about two British geeks called Graham and Clive who travel across America with a passenger.
"It's very funny. I'm perhaps the most pleased with it of anything I've ever done. It's going to be good."
They're due to start shooting it towards the end of this year.
Life's busy for Simon at the moment as he promotes his latest film How To Lose Friends And Alienate People.
It also stars Jeff Bridges and X Files' Gillian Anderson.
Simon's character has a lot of embarrassing moments with famous people, and it sounds like it didn't come naturally for him.
He said: "I personally don't like cringe comedy. I hate embarrassment, I have a thing about it.
Frost and Pegg's project is about two geeks driving across the US
"I can't watch Big Brother contestants being evicted because I can't stand the look on their faces.
"But in this film you kind of take a bit of pleasure in his idiocy."
He's also been filming the new Star Trek movie in which he plays Scotty.
But he's been sworn to secrecy for fear of his life. Or at least his wallet.
He added: "You sign an agreement and if you break it they'll sue you. It's as simple as that.
"If I was to give away a plot detail now I would be in big trouble legally. That's a big incentive."
The actor also told Newsbeat he is actually quite pleased that the American version of his TV show Spaced hasn't taken off.
A US pilot was made, but there's not much chance they will make a series.
He said: "I'd hesitate to sort of cheer just because I know there are obviously other actors involved in it.
"But the fact is it went ahead without our sort of... anything to do with us and we were a little bit disappointed. So the fact that it's not being picked up is good news for us I guess."
