British actor Janet Montgomery has landed a starring role as a young Faye Dunaway in Jonathan Baker’s supernatural love story “Fate,” a film that is shooting in Vancouver for Baker Entertainment.

The film will toggle between a yesteryear version of the character (Montgomery) and a present-day incarnation (Dunaway), spanning much of the protagonist’s entire lifetime. “Fate” revolves around a firefighter (Brandon Routh) who connects with a stranger from the past Tilly (Montgomery) while he’s healing at a rehabilitation center and is transported through time to find the only thing saving his soul — his realization of true love, according to a producer’s logline.

Highland Film Group is selling rights to the $10 million film, which also stars Harvey Keitel, at the Cannes Marche.

Dunaway is on the ground in Cannes, where HBO screened the much-anticipated biographical documentary “Faye.”

Montgomery was cast out of hundreds of actors vying for the role.

“Out of all our cast members, Janet has worked the hardest to embody and challenge her character through Faye Dunaway and into her original performance of young Tilly,” says Baker. “With Janet’s background and chemistry with Brandon Routh, this [will be] an epic love story.”

Montgomery’s credits include everything from “Black Swan” to “Black Mirror.” On the indie film front, she has appeared in such films as “Our Idiot Brother” and “The Space Between Us.” On the small screen, she most recently starred on the British drama “The Ex-Wife” as the titular character.

She is repped by CAA, Hamilton Hodell in the U.K. and the law firm Yorn, Levine, Barnes.
