Little Shop of Horrors (1986) http://www.imdb.com/rg/s/4/title/tt0091419/#lb-vi229310745
A nerdish florist finds his chance for success and romance with the help of a giant man-eating plant who demands to be fed.
This remake features "Rick Moranis [as] nebbishy Seymour Krelborn, who works in a rundown flower shop on Skid Row. While his boss (Vincent Gardenia) bemoans the lack of business, Seymour seeks a way of bringing the shop -- and himself -- fame and fortune. He purchases a strange plant from an even stranger oriental street vendor (Vincent Wong), naming the plant after his girlfriend Audrey (Ellen Greene). Gradually, Seymour learns to his horror that "Audrey II" craves blood and flesh. With each of Audrey II's "FEEED MEEE"s, Seymour must scare up human food to satisfy the plant's appetite. One such victim is dentist Steve Martin, a leather-jacketed Elvis type. The lighthearted tone of the film darkens as Audrey II grows in monstrosity." (1986, USA, 94 mins)
