How Do I ask a guy to sit by me when a large group of friends is going to a movie?

Andyouwonderwhy
A group of like twenty friends of mine are going to see American Sniper. The guy I like is going. He knows I like him but since he found out its just been weird. I kinda want to sit by him...
Do I
A) ask him way before we go
B) Just sit by him when we get in the theatre
C) Just not sit by him and Deal with it

My problem with A & B are that it would be weird and forward. And if A wouldn't be weird how would I go about it. I also don't want him to feel inclined to sit by me just so he doesn't hurt my feelings.

With C, I'm willing to do it but I don't want to lose my chance if I have one.

If you have any other suggestions please offer them up. The movie is at 9 so I need an answer quick!
Ask him way before you go
Vote A
Force yourself upon the seat next to him. (Risking seeming crazy and desperate)
Vote B
Do nothing (and possibly lose my chance)
Vote C
I'll suggest something else
