For his feature film directorial debut Cas and Dylan, actor-turned-filmmaker Jason Priestley struck gold with his two leads: Canadian It-girl Tatiana Maslany and American screen veteran Richard Dreyfuss.

The new movie, now in theatres, follows an unlikely duo who connect on a westbound road trip across Canada.

Priestley was able to nab acclaimed, award-winning Orphan Black star Maslany just before she began her run on the hit sci-fi series.

Meanwhile, Dreyfuss — whose storied career ranges from popcorn favourites such as Jaws, Close Encounters of the Third Kind and Stand By Me to acclaimed turns onstage and in films like The Goodbye Girl and Mr. Holland's Opus — was an out-of-the-blue suggestion that emerged out of Los Angeles.

Priestley recalled being shocked at the notion: "Could we get Dreyfuss? Really?"

"Two days later, I got another phone call: Dreyfuss wants to talk to you."

In the attached video, Priestley talks to CBC's Eli Glasner about Cas and Dylan, landing his leads and the love-hate relationship filmmakers can sometimes have behind the camera.
