Former American President Bill Clinton is reported to have filmed a cameo in Thailand for 'The Hangover 2'.

According to People, Clinton was in Bangkok on Saturday to deliver a speech on clean energy and he also shot his brief appearance on the film, in which he will play himself.

The film, directed by Todd Philips, already made news over cameo appearances when Mel Gibson's cameo was dropped in favour of Liam Neeson, following a decision by the cast and crew not to work with the 'Lethal Weapon' actor.

Mike Tyson will return for the sequel, along with the original stars Bradley Cooper, Ed Helms, Zach Galifianakis and Justin Bartha.
