9 Actors Who Could Completely Ruin Their Upcoming Movies

Casting has always been an absolutely essential part of movie production (duh), but in recent years it's exploded to become a key part of a film's promotion too. It is, after all, where much online chatter comes from - the rumours, the fan picks, the confirmations, the "who it should have beens" - and as such there's increased pressure on making the right choices and then making sure everything's locked down as early as possible (you don't want to have a Tom Hardy leaving Suicide Squad situation).

And, credit where it's due, studios are really nailing it, both in terms of the reveal of information and the casting itself. Marvel in particular get levels of praise comparable to their box office takings for their astute casting across the board, from major headliners to obscure D-List support, and while they've not really hit it out of the park, people are certainly behind some of DC's choices (remember when people weren't too sure about Ben Affleck?). Beyond the geek friendly-franchises though, we're also seeing really strong, non-gimmicky casting for all manner of massive projects.

But casting directors don't always get it quite right, evidenced by several upcoming films with really rather questionable actor choices that may spell doom for the entire project. Here's nine such movies.

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.
