Sweet Repeat: Michael Fassbender’s Intense But Adorable Shark Smile

This photo, plus his predilection for grinning, had fans wanting him to resurrect the role of the Joker after Heath Ledger's death.

Sheepish (but still huge) smile.

Kicking Josh Brolin's ass in Jonah Hex.

Party!smile.

We love him, wrinkles and all.

Sometimes it gets to be too much to hold up those pearly whites.

DUDE THAT'S AWESOME.

There must be photos of puppies with this exact facial expression.

So many LOLs in Inglourious Basterds.

Enjoying his own private joke.
