A Troll in Central Park is a movie starring Dom DeLuise, Cloris Leachman, and Charles Nelson Reilly. An evil Queen banishes a flower loving troll named Stanley (Dom DeLuise) to New York City, where he befriends two young children.
A friendly troll with a magic green thumb grows one flower too many for the queen, whose laws require all trolls to be mean ugly and scare humans whenever possible. As a punishment, he is exiled to a world of concrete, where he should live a life of proper trolldom: Manhattan.
