4. Sylvester Stallone
It is a joke which has been driven into the ground, but I am deadly serious when I say that I struggle to understand what Sylvester Stallone is saying whenever he's on screen. This is not a fantastic trait for someone who seems intent to get the lead in all of the schlocky action films he can rattles out. The man is in fantastic shape for his age, and although he is muscle-bound and rocking a killer bod, it is becoming clearer and clearer to see the pensioner within. Stallone is very keen for us all to watch these throwbacks to '80s and '90s action glory, and for the most part they're good to have a laugh along with. There is a problem, however: most of the films come across as straight comedy due to scenes - such as in Bullet to the Head - where he has an axe fight with Jason Mamoa. Might I remind you that this is the man that played Khal Drogo in Game of Thrones? Anyway, in this sequence, his Dothraki skills have been cast aside, as he simply dances around waiting until the moment where Stallone decides that maybe it's time to call it a day and kill him. I have a lot of respect for Stallone's early output, but in recent years he's really starting to show his age. This is not a crime, of course, but it also doesn't work within the confines of the genre. It's clear he knows this as well because he cast gruff, bald super-cockney Jason Statham in The Expendables to allow for at least some fast paced hand-to-hand. I applaud the sentiment behind Stallone's insistence on cheesy action, but maybe it's time for him to take a step behind the camera.
