With one superhero movie after another, summer moviegoing at the multiplex has become more like a trip to the comic-book store. The Trylon cinema in Minneapolis, however, is reminding viewers that there’s more to comics than Super-, Bat-, and Spider-men. For its repertory series Bif! Bam! Pow! Comic Book Movies!, the theater has sought out less mainstream material, highlighting films that draw on work from independent and underground artists or newspaper comic strips and graphic novels. On June 29 and 30 and July 1, check out Terry Zwigoff’s brilliantly layered documentary Crumb, about Fritz the Cat creator R. Crumb. For a taste of Zwigoff’s intimate portrait of this king of the underground, watch the clip below, in which Crumb reminisces about his unconventional high school crushes.
