According to Patrick Goldstein in The Los Angeles Times, Silver said he showed the movie to Lionsgate and Sony Pictures to get some advice on how to market the film. However, when Goldstein asked Warner Bros.' top executive Alan Horn about the situation, Horn called the movie "very English," not "broadly commercial," and said the studio "might not be willing to spend the marketing money he wants us to." So it follows that Silver probably wants to sell the movie to somebody else.
This kind of thing has happened before. Jonathan Levine's teen horror flick All the Boys Love Mandy Lane was set for a release through The Weinstein Company, but when it was determined that the distributor might not provide the best home for the film, it went to the more agreeable Senator Films (although Senator has yet to release it). What troubles me is Horn's assertion that RocknRolla is "very English." Yeah ... so?
