9 Actors Who Could Completely Ruin Their Upcoming Movies

9. Charlie Hunnam - Arthur Pendragon (King Arthur: Legend Of The Sword)

The biggest WTF casting in the King Arthur reboot nobody (probably not even Guy Ritchie) wants is most certainly David Beckham, either an odd show of nepotism or an ever stranger studio cash-grab. But that's just a few-day cameo. If we're talking movie ruining, then we need to look at the titular hero.

Like countless TV actors before him, Charlie Hunnam hasn't really been able to transfer the success of Sons Of Anarchy into a strong movie career, with a bland turn in Pacific Rim, and he just looks wholly unsuited to be leading the Knights of the Roundtable. The Comic-Con trailer showed him playing the legend like a geezer recounting the Lock, Stock gang's escapades before entering into generic action, which makes Disney's The Sword In The Stone look like a documentary.

Sure, this isn't the classic Arthur - the trailer was so Ritchie-fied it was barely clear it's intended as a period piece - but Hunnam doesn't appear to have the chops to blend the director's style with the weight of the myth surrounding him. That's not to say the film looks great regardless, but he's got a big task on his hands.
