Also Affleck as Jack Ryan on Sum of All Fears
Alec Baldwin as Jimmy Doolittle in Pearl Harbor. (And Affleck too, but that goes without saying)
Willem Dafoe as John Clark (aka John Kelly) in Clear and Present Danger. Ruined the whole movie for me...I've had a huge crush on Clark since I met him in the books and Dafoe is NOT Clark.
Alec Baldwin and Ben Affleck were bad choices as well. Those three were an affront to all Clancy books.
Yes, truly not believable. Not even slightly believable. I watched and pretended it was not the real Jack Ryan. And tried to enjoy the rest of it...
"Also Affleck as Jack Ryan on Sum of All Fears"
Affleck in ANY role as a straigh male.
