Prior to Chris Evans landing the role of Steve Rogers, John Krasinski was up for the role of Captain America.

Krasinki appears on Conan O'Brien tonight where he talks about screen testing for Cap.

Watch the video below where John Krasinki says Marvel let him put on the suit, and then Thor himself Chris Hemsworth walked by!

I think Krasinki was also up to play Star-Lord.

Conan O'Brien airs weekdays at 11pm ET on TBS.
