Few, I believe, will disagree that there is histrionic talent in England’s Natalie Dormer. She gets the chance to do a lot in a 13-minute short by one Erin Cramer—“The Ring Cycle” (2014, available on YouTube)—with its successful blend of mild comedy and melancholy drama. Versatile Dormer is moving, suggesting a wave of emotion cresting in her but never breaking. Her character is Millie, who happily receives a wedding ring from Richard (Emun Elliott, also good) who soon discontentedly renounces the marriage. But Millie cannot discard the ring. There is economical art here—the movie is almost too short—with Cramer and Dormer making a fine team.
