Seth Rogen provided the voice of Mantis in Kung Fu Panda
Canadian actor Seth Rogen has said that one of the drug scenes from his new film Pineapple Express had to be specially edited for UK audiences.
The film sees Rogen star as Dale Denton who tries out a rare strain of cannabis, only to witness a murder and leave evidence at the scene.
He said: "We had to remove stuff from the movie to get the rating that we needed.
"We're actually more responsible in the UK than we are in the States."
The film is rated R in America, which means you have to be over 17 to see it. But in the UK it's got a 15 certificate.
Rogen, who's also starred in Knocked Up and Superbad, said: "There's a scene in the movie when we sell [drugs] to high school kids - that's still in there I assume.
"But in the American version of the scene we also smoke weed with them and hang out.
"It's a really explicit scene of us getting high with these 11-year-olds. I think for the UK they've kind of softened it a bit."
Rogen isn't worried about the content of the movie for US audiences though.
He said: "We had no moral obligation with this movie. I mean it's an R-rated movie, you have to be 17 in order to see it so we figure at that age you're an adult."
"I've been seeing R-rated movies since I was 12 years old and I'm OK! Not really."
Pineapple Express is released in the UK on 12 September.
