Brad Pitt touched down in Richmond, London, this evening in his helicopter. He was only on the ground for a short time and left again after picking up Angelina Jolie. She was out taking care of business earlier in the day when she took a meeting in central London. Soon, though, Brad's expected to depart the UK in order to travel to Canada for the Toronto Film Festival. He'll promote Moneyball, which also features Jonah Hill. Jonah spoke about Brad on set in a recent interview, revealing that the older actor definitely loves to play pranks on set. Speaking of a particularly good joke, Jonah said of Brad, "He started messing with [my golf cart] and eventually turned mine into a full-fledged Wham! mobile — the band Wham! — where eventually there was a bigger-than-life-sized portrait of myself as a member of Wham! next to George Michael on the front of it. It was bright pink, and eventually, by the end, if you turned on my golf cart, it blasted 'Wake Me Up Before You Go-Go' and could not be turned off unless the engine was turned off. Sometimes I feel like he has a team of scientists working on f---ing with me."
