Three. He played Jack Ryan twice.
One could argue that he doesn't have a ton of range as an actor, but his filmography is ridiculous. Aside from the franchises already mentioned, he was in American Graffiti, Witness, Working Girl, Air Force One, The Fugitive. Also had small roles in Apocalypse Now and The Conversation.
