If you were a Dawson's Creek fan, chances are good that you caught James Van Der Beek in Varsity Blues, a 1999 high school drama about the pride and peril of playing for a football team in Texas. But would the film have been the same if it had been Jason Segel uttering the line "I don't want your life" instead of Van Der Beek? On Letterman last night, Segel explains that he was very close to nailing the role before Dawson stepped in. (Bonus: he also discusses what drove him to drop 25 lbs. after filming Bad Teacher.) Watch!
