I thought some of the types/relations in this movie were very clear.

Ben Gates: ENTp
Abigail Chase: ISTj
Patrick Gates: ESFj
Riley: no idea
Sadusky: ESTp
Emily Appleton: xxTj
the president: ESFp (maybe ENFj?)
Mitch Wilkinson: Gamma SF, probably ISFj

The supervisory relationship between Ben and Abigail is especially obvious - and leads to hilarious results, of course.

Also, I think Harvey Keitel could easily be ESTp himself, since all his roles seem pretty much the same as this one.

I'm stumped on Riley. He's extremely psychologically immature and lacks anything remotely like self-confidence, which doesn't say anything about his type. The only other thing to go on is his relationship with Ben.
