It's the film Quentin Tarantino fans have spent the best part of a decade waiting for. The latest word from Michael Madsen is that the proposed Pulp Fiction and Reservoir Dogs spin-off, featuring Madsen and John Travolta as the Vega brothers, could be heading for production after all.

The idea originally formed in Tarantino's mind because Vincent Vega from Pulp Fiction and Vic Vega from Reservoir Dogs had always been conceived as siblings. But with both characters having been killed in their respective films, the only possibility appeared to be a prequel, which was looking less and less likely given the advancing years of Travolta, 51, and Madsen, 48. According to Madsen, however, the maverick director has come up with an ingenious plan to make the film happen after all. He told Moviehole.net: "Well, first he said he would do it, then he said he wasn't going to do it. Then he called me and said, 'You know, I've figured out a way to do it. It can't be a prequel because you and John don't look the same. "It wouldn't make sense as a sequel because you're both dead.' And he gave me an idea that would be really outrageous - that John and I would be the twin brothers of Vic and Vincent. We come from Amsterdam to LA to avenge the deaths of our brothers. I think that's pretty interesting. For me, I'd love to do it." In the meantime Madsen fans will have to be content with the fact that the actor is currently preparing to reprise his role as Bob in Sin City 2.
