Canadian filmmaker Sarah Polley is dissociating herself from her latest film, slated to air in Canada during the upcoming Academy Award broadcast.

In a statement released Tuesday, the Toronto-based actress and director said she is pulling her name from the two-minute short The Heart, which she created for the Heart and Stroke Foundation, because she's learned it will also promote "a product."

The foundation's healthy living campaign is sponsored by margarine and oil company Becel.

Initially, "I was thrilled, as I was proud to be associated with the work of this incredible organization," Polley said of her involvement with the Heart and Stroke Foundation.

"However, I have since learned that my film is also being used to promote a product. Regretfully, I am forced to remove my name from the film and disassociate myself from it."

A longtime political activist, Polley added that she'd "never actively promoted any corporate brand, and cannot do so now."

The Heart, filmed in late 2009 and starring Sarah Manninen and Jean-Michel Le Gal, is set to air Sunday night as part of CTV's broadcast of the Oscar gala. It is scheduled for broadcast during a commercial break.

Polley rose to fame with her starring role on TV's Road to Avonlea and in films like The Sweet Hereafter, Go and My Life Without Me. More recently she has won acclaim for her work behind the camera, including the 2006 film Away From Her, her feature directorial debut for which she was an Oscar-nominee for her adapted screenplay.
