Michelle and Sarah: Waltzin' Co-Stars

Buddying up for their filming duties, Michelle Williams and Sarah Silverman were spotted on set of “Take This Waltz” in Toronto, Canada on Wednesday (August 4).

The “Shutter Island” babe and the “Comedy Central” funny woman were hard at work, shooting scene after scene and seeming to be enjoying themselves along the way.

Ms Williams took her usual blonde locks to a reddish, auburn color for the drama film, which also stars Seth Rogen.

According to IMDB, “Take This Waltz” is "a funny, bittersweet and heart-wrenching story about a woman struggling to choose between two different types of love."
