Corner Gas‘ Eric Peterson and Aaron Poole (Copper) have joined the cast of Jason Priestley’s Cas & Dylan now shooting through Sept. 25.

They join leads Richard Dreyfuss and Tatiana Maslany in Priestley’s narrative directorial debut that is based on a comedy script from Jessie Gabe (Being Erica).

Cas & Dylan follows a dying doctor (Dreyfuss) whose plan to check out on his own terms takes a reluctant turn when he inadvertently winds up on the lam with a young 22-year-old woman, played by Maslany.

The Canadian indie, produced by Mark Montefiore (Picnicface), is shooting in Ontario and western Canada.

Cas & Dylan has financing from Telefilm Canada, the Northern Ontario Heritage Fund, the Alberta Media Development Fund and The Harold Greenberg Fund.

Pacific Northwest Pictures is releasing the picture in Canada, and the U.S. and international sales rights are with Breakthrough Entertainment.
