Boxing clever: Michelle Williams and Luke Kirby fit in a quick exercise session between takes on the set of Take This Waltz
Actors often complain that the waiting around between movie takes is boring.
So Michelle Williams put the time to good use on the set of Take This Waltz in Toronto.
The Brokeback Mountain star was spotted jogging and shadow boxing with her co-star Luke Kirby during a break in filming today, culminating in a congratulatory high five once the exercise session was over.

The two were still in their characters' wardrobe as they larked about in the Canadian sun.
Romantic drama Take This Waltz, which shares its name with a Leonard Cohen song, also stars comedian Sarah Silverman and Knocked Up star Seth Rogen.
Williams, 29, plays a married woman who begins a flirtation with one of her neighbours, played by KIrby, after meeting him on a business trip.
Rogen plays William's husband.
The Dawson's Creek star is in town with her 4-year-old daughter Matilda, whose father is the late Heath Ledger.
