Scott Andrew Caan (born August 23, 1976) is an American actor. He currently stars as Detective Danny "Danno" Williams in the CBS television series Hawaii Five-0 (2010–present), for which he was nominated for a Golden Globe Award. Caan is also known for his recurring role as manager Scott Lavin in the HBO television series Entourage (2009–2011). He was also a part of 1990s rap group The Whooliganz with The Alchemist. The duo went by the names Mad Skillz and Mudfoot, respectively.
Caan was born in Los Angeles, California, the son of actor James Caan and Sheila Marie Ryan, an actress and former model. His paternal grandparents were Jewish immigrants from Germany. He has an older half-sister named Tara Caan and three younger half-brothers named Alexander James Caan (born 1991), Jacob Nicholas Caan (born 1995), and James Arthur Caan (born 1998).
Caan was a roadie for the rap groups Cypress Hill and House of Pain. Caan was also a member of the hip-hop group The Whooliganz (with producer and fellow MC the Alchemist). The Alchemist and he, when performing as the rap duo the Whooliganz in the early '90s, received a record deal with Tommy Boy records. They recorded the album Make Way for the W., but after their first single "Put Your Handz Up", the album was shelved and the duo was dropped by Tommy Boy. In 1995, the Whooliganz' song "Whooliganz" was released as a single in the UK, but Caan and the Alchemist had already parted ways. Caan reunited with his former partner The Alchemist in 2014 on the Step Brothers project Lord Steppington, performing in the song "Byron G" with musician Evidence.
