Deborah Proby of the Raven’s Cry Theatre in Sechelt, B.C., says in an email she won't show the film.
The black-and-white decision that's receiving coverage in B.C. media outlets appears to be tied to the movie's 18A rating, which Proby says would have forced her to sell tickets to minors.
She says adults can still find many other ways to see the movie, just not at her theatre.
Proby says she doesn't wish to "save the world," and did not intend to trigger a reaction.
The move, which opens in theatres on Friday, is an adaptation of the E L James book about a college student and her torrid affair with a 27-year-old billionaire with a penchant for bondage, discipline, sadism and masochism.
