When The Office premiered in 2005, John Krasinski [1] was a 25-year-old unknown actor whose biggest roles to date included "Messenger No. 3" in 2004's Taxi and "Flea Club Candidate 1" in 2002's Alma Mater. By the time The Office aired its last episode in 2013, John was a bona-fide movie star married to fellow A-lister Emily Blunt [2] and — oh yeah — incredibly hot [3]. The actor's 15-year journey from goofy, floppy-haired Jim Halpert [4] to totally jacked Jack Ryan is seriously impressive, and we think the best way to celebrate it is to take a stroll down memory lane with these 44 adorable throwback pics.
