You should watch Dogma, I know it's been quite a while but he's absolutely hilarious in it.

The character is a clown who is stuck in a serious situation. He's a funny guy, a joker, and that keeps him alive.

Matt Damon is a serious actor, who can do a serious character. Put a serious character into a funny situation, and it can be very funny. But put a serious character actor into a funny man role, and well... I'm hopeful, but worried.

You didn't say 'bless you' when I sneezed.

It's Ridley Scott doing a Mars shipwreck movie. I hope the humour is at a minimum.

It wont be a very accurate adaptation if it is! Mark Watney's a fun guy!

In my head Mark Watney was Sam Rockwell, maybe beacuse of Moon , similar theme different plot.
