John Krasinski: Then
John Krasinski beat out the likes of Adam Scott and John Cho for the part of Jim Halpert, his first major acting role. Krasinski’s iconic “Jim Looks” at the documentary cameras have spawned countless GIFs, and his will-they-or-won’t-they chemistry with co-star Jenna Fischer as Pam Beesly formed the beating heart of the show’s early seasons. The culmination of their love story with their wedding in Season 6 was one of the most memorable moments of the series.
