Maggie McOmie is an American stage and film actress, best known for co-starring with Robert Duvall in the 1971 film THX 1138. For the film, she was required to shave her head, an event that was featured in a tongue-in-cheek behind-the-scenes featurette titled Bald. McOmie was one of the few actresses approached for the part of THX's lover, LUH, to agree to cut her hair for the role.
