Never one to avoid the limelight, Jack Black strikes a pose for photographers at the UK premiere of new comedy Tropic Thunder - the film opens across the country on 19 September.
The movie is about a group of actors making a war film who get caught up in a jungle battle with a drugs gang. Ben Stiller and Robert Downey Jr play the other two main characters.
Stiller also directed and co-wrote the movie. Despite attracting controversy, the film was a hit in the US and topped the box office for its first three weeks of release.
Robert Downey Jr's character pokes fun at the lengths some method-actors go to when they take on a role. He plays an Australian actor who puts on make-up to portray an African-American.
