Two hippies from the 60s (Eric Roberts and Cheech Marin) emerge from a Central American jungle, where they’ve been smoking dope and hiding from the feds, come to New York, and discover what the U.S. in 1989 is all about. Aaron Russo (Bette Midler’s former manager) and David Greenwalt codirected this comedy from a script by Neil Levy and Richard LaGravenese; Julie Hagerty and Robert Carradine play the heroes’ now-yuppified friends who are gradually inspired to return to their former values. As disheveled in some ways as its leading characters are, this movie is still something of a rarity: a sincere, somewhat nuanced, relatively uncliched, and actually judicious look at both the 60s and 80s and what they mean in relation to each other. A far cry from the more reductive treatment of these issues in various sitcoms, this movie is genuinely interested in the question of what happened to 60s ethics, and in spite of an occasionally awkward plot that weaves in and out of comedy, it manages to come up with a few answers. The costars include Louise Lasser, Cindy Williams, Cliff De Young, Andrea Martin, and Buck Henry; the latter two are especially funny in the one extended sequence in which they appear. (JR)
