Before Little Shop of Horrors was a beloved musical, it was a low-budget black comedy shot in two days by the legendary Roger Corman. The plot is definitely darker than that of the musical version. Seymour is a meek young assistant in Mushnick's flower shop who cross-breeds two plants and ends up with a killer hybrid. Seymour accidentally kills a few people (you know how it is), and feeds their corpses to the exotic Venus flytrap-style plant he’s named Audrey II after his crush, the beautiful shopgirl Audrey. The police start tracking all these missing people, and fortuitously end up at Mushnick's shop just as Audrey II's buds are about to open. Things really get grisly from there. The Strange Brew division of the Webster University Film Series presents this dark slice of 1960 horror at 8 p.m. Wednesday, July 11, at the Urban Chestnut Grove Brewery (4465 Manchester Avenue; www.webster.edu/film-series). Admission is $5.
