Callum Keith Rennie makes uneasy company worth watching, bringing a worn, disaffected edge to supporting roles. We rate him most when the tough exterior has something behind it, as it does with Leoben in Battlestar Galactica.
Fi1m perspective
Callum Keith Rennie's characters often seem tired of other people, and liable to make that somebody else's problem. The philosophical Cylon Leoben in Battlestar Galactica (2004) is a good use of that unease: the character's beliefs matter as much as his capacity to trouble us. We rate Rennie in parts like this, where being difficult does not exhaust what there is to play. The series earns its seriousness through tense storytelling, though its persistent gloom can become wearing.
His breakthrough parts offered different settings for that edge: punk rocker Billy Tallent in Hard Core Logo (1996), then Detective Stanley Kowalski opposite Paul Gross in Due South (1997–99). Don McKellar's apocalyptic Last Night (1998) also made room for his understated supporting work. Wider international recognition did not mean abandoning Canadian independent films. He has continued to mix those with genre television and international supporting parts, rather than settling into one sort of production.
Memento (2000) puts Rennie's Dodd among the supporting characters surrounding Guy Pearce's vulnerable Leonard. We were frightened by Christopher Nolan's backwards storytelling because it made Leonard's memory loss a difficulty we had to share. Rennie's disaffected edge fits that uncertainty, and the dark humour keeps the film from becoming a solemn demonstration of clever plotting. Some supporting characters do exist chiefly to keep us guessing, though. The film is an excellent introduction to him, provided we remember that Pearce carries it.
The reservation is the casting habit: tough, edgy outsiders can become familiar before a scene has properly started. His preference for minimal dialogue and image-based acting makes sense, but the writing still has to supply something beyond a difficult manner. We would rather see him given more parts with Leoben's ambiguity than another opportunity to look like trouble. We would start with Memento, then make time for Battlestar Galactica when we feel equal to a persistently bleak series.
