Career: Vaughn was written into Swingers (1996) by Favreau to play the character of Trent. It was a critical success and led to Steven Spielberg casting Vaughn in the big-budget sequel The Lost World: Jurassic Park in 1997. He spent the next decade notching up hit after hit, from heavyweight dramas like Return to Paradise (1998), through to comedy fare like Old School (2003), Dodgeball: A True Underdog Story (2004) and Be Cool (2005). He is considered the leader of, what the media refers to as, 'The Frat Pack,' along with Will Ferrell, Jack Black, Ben Stiller, Steve Carell and Owen and Luke Wilson. His other film credits include The Break-Up (2006), Into the Wild (2007), Fred Claus (2007), Four Christmases (2008), Couples Retreat (2009), The Internship (2013) and Delivery Man (2013).
