10 Actors Who Were Criminally Wasted In Famous Movies

There's having your talent thoroughly wasted by the time a feature is unleashed onto the general public, and then there's having your talent not even make it into the finished film at all.

That's the unfortunate position the Golden Globe nominated Sienna Miller found herself when the Johnny Depp-starring Black Mass was released back in 2015. Cast in the role of Whitey Bulger's late girlfriend Catherine Greig, Miller worked for four days on set as the character/real-life figure who eventually went on the run with the infamous mobster.

However, whilst editing the flick, director Scott Cooper had a change of heart. Instead of including the period of Bulger's life that involved Greig in his feature, he opted to focus solely on his life in Boston in the time before he did a runner.

This meant that the brilliant Miller, showing up to film immediately after wrapping on American Sniper, was completely sliced out of the eventual finished article. Despite admitting that her role was only intended to be a cameo at first, before being fleshed out as they shot, Miller's presence in the feature would've no doubt been a welcome one had she not been given the unceremonious heave-ho.
