Q (also known as The Winged Serpent and as Q - The Winged Serpent) is a 1982 horror film written and directed by Larry Cohen and starring Michael Moriarty, Candy Clark, David Carradine, and Richard Roundtree. The original music score was composed by Robert O. Ragland. The film was marketed with the tagline "It's [sic] name is Quetzalcoatl... just call it Q, that's all you'll have time to say before it tears you apart!" Roger Ebert gave the film 2 and 1/2 stars in his original review but was bursting with praise for Moriarty's performance. He relates the anecdote that, when movie reviewer Rex Reed met Q's producer, Samuel Z. Arkoff, Reed told him "What a surprise! All that dreck--and right in the middle of it, a great Method performance by Michael Moriarty!" Arkoff replied "The dreck was my idea."
