David Rysdahl as Donald Hornig

David Rysdahl as Donald Hornig in Oppenheimer; remember when he was in 'The Family?' now he's in something BIG. Making waves in physics and still rockin' the boyish charm.

Example of how it's used in a sentence:

Person 1: Who's the guy looking like he's solving the universe in Oppenheimer?

Person 2: That's David Rysdahl as Donald Hornig, dude! From 'The Family' to atom bombs.
