JUSTIN Timberlake is set to star in one of Guy Ritchies new movies. The SexyBack singer met the British film director at his London pub The Punchbowl on Monday and the pair discussed working together. A source said: Work is really taking off for Guy at the moment and he is lining up talent for projects in the pipeline. Guy and Justin have known each other for a while through Guys ex-wife Madonna. Guy thinks Justin - who has previously appeared in 2006 film Alpha Dog - would be perfect for his big-screen version of musical Guys And Dolls or a remake of the classic war film Wild Geese. The source added to Britains The Sun newspaper: Justin would be ideal for Guys And Dolls because he can act, dance and sing. He would be a great box office draw into the bargain, as well as a safe bet to sell the soundtrack. As well as discussing future projects, Justin and Guy - who became friends when Justin worked with Madonna on hit single 4 Minutes - drank pints of lager, before performing a few songs as they strummed on a banjo and a guitar. An onlooker said: Justin got there about 11.30pm. Guy had been there since 8pm and the night quickly got very merry. At one point they were in such high spirits, Guy picked up a banjo and handed Justin a guitar and they had a little singsong. - ES
