The wins cap a triumphant run for “Witch,” which world-preemed in competition in Berlin last year and has gathered kudos around the world. It opened in the U.S. this weekend.

James Cromwell won best actor for his perf in Michael McGowan’s “Still Mine.” The Academy of Canadian Cinema and Television’s inaugural CSAs replace the Geminis (TV) and Genies (film).
