Erik Per Sullivan

Sullivan was born on July 12, 1991 in Worcester, Massachusetts, the only child of his mother, Ann, born in Sweden and naturalized as a US citizen in 2007, and Fred Sullivan, of Irish descent,[1] who owns a Mexican eatery called The Alamo.[2][3][4] He speaks a little Swedish,[5] and his family visits Sweden almost every year.[6] At a young age he began studying piano and the saxophone.[7] He has a first-degree black belt in taekwondo.[8]

Sullivan studied at the Mount Saint Charles Academy, in Rhode Island, and Phillips Exeter Academy in New Hampshire. Beginning in 2009, he attended the University of Southern California in Los Angeles.[9]

Sullivan has played a variety of characters in film and on television, including the title role in the independent film Mo, and voicing Sheldon the Seahorse in both the animated film and the video game Finding Nemo. He also had a starring role in the movie Christmas with the Kranks.

From January 9, 2000, to May 14, 2006, Sullivan played Malcolm's younger brother Dewey in the Fox sitcom Malcolm in the Middle. In 2005, along with Malcolm co-star Jane Kaczmarek, he wrote the afterword to the children's book Together, which is about farming and was inspired by the nonprofit organization Heifer International.[10]

Sullivan's last known acting credit was an appearance in the 2010 film Twelve. He has since kept a low profile, being notably absent from several Malcolm in the Middle cast reunions.[11]
