According to his autobiography, Roger Corman took LSD while preparing to make this film, which claims to show what an acid trip is like. Hallucinogenic accuracy aside, The Trip is an entertaining period piece and perhaps the ultimate late 1960s hippie exploitation flick. The final shot, tacked on against Corman's wishes by American International Pictures, awkwardly suggests that Paul Groves (Peter Fonda) has destroyed his mind on the drug, but The Trip is neither clearly pro-drug nor clearly anti-drug; Paul is visited by visions both beautiful and horrifying while under the influence, and the film seems to argue that drug use should be an individual matter. Corman was always a cannier visual stylist than his low-budget brethren, and most of The Trip plays like an excuse to throw interesting images on the screen; it might not look quite like an acid trip, but it is better to look at than the glut of "youth on drugs" films that followed it. And the participation of Fonda, Jack Nicholson, Dennis Hopper, and Bruce Dern gives it all the hipster credibility you could ask for.
