He also performed with Boom Chicago in Amsterdam before joining The Second City Touring Company.  In the early 2000s, he was among the founding company members of The Second City Las Vegas, where he performed in The Best of The Second City and The Not Ready For $3.99 Prime Rib Players.

Sudeikis joined the writing staff of Saturday Night Live In 2003. He became a featured player in May 2005 and earned repertory status for the 2006, where he remained one of the cast’s most visible and versatile performers until his departure in 2013.

Sudeikis’ extensive TV credits include NBC’s 30 Rock, where he played “Floyd,” love interest of fellow Second City alum Tina Fey’s character “Liz Lemon,” Eastbound & Down, It’s Always Sunny in Philadelphia, The Last Man on Earth, and more.

He has also starred in a number of top comedy movies, including Hall Pass, We’re the Millers, Horrible Bosses 1 and 2, Masterminds and others. He also voices parts in animated projects including TV series The Cleveland Show and video game Grand Theft Auto IV.

Sudeikis served as Roastmaster in the September, 2017 benefit I Can’t Believe They Wendt There: The Roast of George Wendt. The event, which was Second City’s first celebrity roast, raised more than $200,000 for Gilda’s Club Chicago and The Second City Alumni Fund.
