by Chris Carpenter Take one of gay writer Bret Easton Ellis’ novels, a twist of Alfred Hitchcockian femme fatale/double life sensibility, European indie filmmaking realness, and a lot of male-on-male sex. Shake vigorously, pour, and you will end up with Sebastian, an engrossing new movie from the writer-director of 2018’s acclaimed gay romance, A Moment in the Reeds. It opens in US cities beginning Friday, August 2.
