Ah, to be young and in a Richard Linklater movie. Our premier chronicler of laid-back youth is at his best in Dazed and Confused and School of Rock, which play at the New Beverly on 35mm. The writer-director's last-day-of-school saga may be the definitive "hangout movie," an overused term of late but one that perfectly describes this banter-heavy ode to youth. School of Rock, meanwhile, features the definitive Jack Black performance. Linklater grew a lot as a filmmaker in the decade that separates these two films, but both make it clear that, in good times and bad, you just gotta keep L-I-V-I-N.
