Patrick John Flueger is an American actor best known for his starring role as returnee Shawn Farrell on the science fiction television series The 4400, from 2004-2007.
He also has a starring role as Adam Ruzek, a young undercover patrolman recruited by Olinsky to do undercover work, in the police procedural television drama series Chicago P.D..
Flueger received his big break when he auditioned for the 2001 family hit, The Princess Diaries. He and four others competed for the leading male role, but that part went to Robert Schwartzman. Patrick made his mark with director, Garry Marshall, though, and Marshall wrote him a part as Jeremiah, a fun-loving card-trick master who charmed the lead character's best friend.
He has made guest appearances on a number of television shows including Judging Amy, CSI: Miami, Boston Public, JAG, It's All Relative and Law & Order: Special Victims Unit.
His film resume includes Mother's Day, the Footloose remake, the Jim Sheridan-directed Brothers and the Anthony Hopkins-starrer The World's Fastest Indian. He made his motion picture debut in 2001 in Disney’s The Princess Diaries.
He also appears in the independent films Loaded, directed by Chris Zonnas; and San Patricios, which is set in South Texas and centres around the relationship between two brothers.
Flueger is a graduate of Red Wing High School in Minnesota and has two younger siblings.
