After almost a decade of starring in failed pilots, Toronto-born Will Arnett finally hit pay dirt in 2003 when Fox picked up Arrested Development, an irreverent sitcom that cast him as a spoiled rich kid-turned-struggling illusionist. While the show struggled in ratings, it won loads of critical praise and garnered an incredibly loyal fan base that helped keep it on the air for three seasons before Fox finally gave up and pulled the plug. In the wake of Arrested Development's cancellation, Arnett quickly and smoothly transitioned into big-screen work. His first starring role came in 2006 with the comedy Let's Go to Prison! Though the film failed to find success at the box office, Arnett's momentum wasn't hampered in the least. In 2007, his film career exploded with supporting roles in Blades of Glory, Hot Rod, and Ratatouille, and a starring slot opposite Saturday Night Live's Will Forte in The Brothers Solomon. That same year also saw Arnett turning in a scene-stealing guest spot on NBC's 30 Rock and a memorable voice-over cameo in Edgar Wright's faux-trailer contribution to Grindhouse, "Don't."
Thanks to his distinctive deep voice, Arnett found steady work in animated films including Ratatouille, Dr. Seuss' Horton Hears a Who, Monsters vs. Aliens, Despicable Me, and The Secret World of Arietty. He had a failed sitcom, Running Wilde, in 2010 that was cancelled after just one season, but he quickly found himself as the lead on the NBC sitcom Up All Night opposite Christina Applegate, a show that did earn a second season.
In 2003 he married Saturday Night Live star Amy Poehler, his second marriage after a brief union with Penelope Ann Miller that lasted less than two months. ~ Matthew Tobey, Rovi
