Five Easy Pieces is the nominal sibling to Easy Rider, which put Jack Nicholson a step from stardom in 1969. But Pieces, this 40th-anniversary reissue reminds you, was a very different film. The soundtrack is Patsy Cline, not Steppenwolf, and we first see Nicholson working in a hard hat, the music and garb of pro-‘Nam hippie-bashers in 1970. But the cultural action is mostly in Nicholson himself, and the simmering storm of dissatisfaction and high intelligence in his odd-angled, lean face, not often inclined here to split into that trademark super-smile.
