Trigger is a 2010 Canadian comedy-drama film directed by Bruce McDonald and starring Molly Parker and Tracy Wright as Kat and Vic, former rock stars reuniting their band Trigger for the first time since their retirement.The film was originally planned in the late 1990s as a companion film to McDonald's Hard Core Logo, which would have starred Hugh Dillon and Callum Keith Rennie. However, work on the film remained dormant until McDonald and screenwriter Daniel MacIvor decided to rewrite their original screenplay to be about two women instead. Rennie does, however, appear in the film as his Hard Core Logo character Billy Tallent.

The film's cast also includes Daniel MacIvor, Don McKellar, Sarah Polley, Lenore Zann, Carole Pope and Julian Richings. Brendan Canning of Broken Social Scene wrote the film's score.
