Jack Black on Tropic Thunder

Updated 09.29 Sun Sep 21 2008

Star Jack Black spills the beans on his latest movie Tropic Thunder.

The new action comedy makes fun of the Hollywood industry.

"Tom and I never shared the screen, but I did see him at the read through a couple of years ago and he is very charismatic and funny" - Jack Black

The plot centres on a group of pampered actors with huge egos who sign up to star in the Vietnam War.

The director instead drops them into a real danger zone, with only their fake weapons.

Ben Stiller who stars and directs in the movie has been working on the script for a decade.

Jack Black, who plays a lowbrow comedy star suffering from heroin withdrawal, says Ben was a great director 'who never cracked the whip and infuriated me'.

Tom Cruise, Nick Nolte and Robert Downey Jnr also star in the parody film.

Black said of Cruise: "Tom and I never shared the screen, but I did see him at the read through a couple of years ago and he is very charismatic and funny."
