LAS VEGAS: Heather Graham thinks Las Vegas is ‘’phony’’. The actress returned to the US gambling capital to film the third installment of ‘The Hangover’, but finds it too superficial for her taste. She said: ‘’I don’t like Vegas. People seem phony, they’re spending all their money and it’s sad. It’s also so cold with permanent air conditioning everywhere. I’m more the type who wants to be outside and look at a tree. I don’t want to look at a machine.’’ Although she didn’t enjoy the location, Heather especially liked the luxury trailers, stayed there during filming.–ES
