Even though he's a big star these days and you might think that the very mention of his name in connection would a project would get the green light flashing, even Depp has seen some past and future films plunged into limbo.

The most famous recent example was Shantaram, which has been in the works for around four years, even since Depp committed to starring in the adaptation of Gregory David Roberts' novel.

The tale of a man - based largely on Roberts' experiences - who dabbles in organized crime and time as a slum doctor - has been through the wringer already, with Peter Weir (above) at one time signed to direct. But then… "Peter moved on from this film because his interpretation of it differed greatly than that of the studio and producers," was the official story.

The last big name to be attached was Mira Nair, but she moved on to make Amelia. So Shantaram sits, waiting for some action…
