Question: who plays seymour in little shop of horrors
Answer: Rick Moranis

title: Little Shop of Horrors (film)
text: The film's original 23-minute finale, based on the musical's ending, was rewritten and reshot after test audiences did not react positively to it. For years only available as black-and-white workprint footage, the original ending was fully restored in 2012 by Warner Home Video. In the early 1960s, a three-girl "Greek chorus"—Crystal, Ronnette, and Chiffon—introduce the movie, warning the audience that some horror is coming their way ("Prologue: Little Shop of Horrors"). Seymour Krelborn (Rick Moranis) and his colleague, Audrey (Ellen Greene), work at Mushnik's Flower Shop in a run-down, rough neighborhood in New York City referred to as "Skid Row".
