Boosting feather-light Heather Graham into a horizontal position was a cinch for her screen colleagues, as they helped her recline in the air at the presentation of their new filmThe Hangover in London's Leicester Square. It was another story when the Baby On Board's co-stars tried the same trick with the considerably heavier Zach Galifiankis.
The group's lighthearted antics outside the cinema were in keeping with the zany plot of the film, a tale of stag-night capers gone horribly wrong.
Glamorous Heather plays a stripper who gets mixed up with a group of buddies on a road trip to Las Vegas two days before their friend's wedding. Their night to remember turns out to be one they forget - literally.
They all wake up the next day in a Caesar's Palace hotel suite which is looking decidedly the worse for wear and has a tiger in the bathroom. The groom, meanwhile, is nowhere to be seen.
Over the next 24 hours they try to locate the missing groom and get him to the church on time. Their adventures also involve an encounter with former heavyweight boxing champ Mike Tyson, who appeared as himself in the movie.
