Ben Stiller's 'talked the head' of fans at the premiere of his new film, Tropic Thunder...

He spent over an hour chatting on the red carpet in London last night.

He's clearly been taking tips from his friend Tom Cruise who is famous for mammouth sessions on the red carpet.

The Top Gun star makes a cameo in the comedy action film in a fat suit.

Ben says surprisingly, Tom didn't take much convincing.
