Actor: Jack Black

Jack Black fronts Tenacious D with Kyle Gass, which began as a comedy act and became a genuine touring band with several albums.

High Fidelity gave him the role that made him famous, a record shop clerk of total contempt, and School of Rock built an entire film around the energy. Bernie, for Richard Linklater, is the dramatic performance worth seeking, playing a real mortician convicted of murder whom his town defended.
