8 Actors Who Will Ruin Upcoming Films

Admittedly this is a contentious one because nobody really wants to see a Terminator film without Arnold Schwarzenegger in it. They tried that before, and it didn't work.

But here's the thing, T6 finds itself in something of a catch-22 situation because it's unlikely to work with Arnie now that he's over 70 years of age.

There are two possible ways the sequel might use him. He could play an ageing T-800 again, like he did in Genisys, or he could portray the human these Terminators were originally based on, something James Cameron has strongly hinted at in interviews.

Neither of those scenarios are going to go down well. Arnie was unconvincing as a geriatric killing machine in the last movie, but having him in a Terminator movie in a non-Terminator role would be too distracting and just wouldn't sit right.

Playing human characters has never been Schwarzenegger's strong suit, unless they're clobbering hordes of bad guys and cracking one-liners. The T-800 role was tailor-made for him because he's an expert at stoic facial expressions and deadpan delivery.

It seems Cameron has cast Arnie in T6 purely because he feels he has to.
