Julianne Moore, Liam Neeson and Amanda Seyfried have signed on to star in Atom Egoyan's upcoming thriller "Chloe."

According to Variety, the film follows a doctor (Moore) who hires an escort (Seyfried) to test her husband's (Neeson) fidelity. Things start to heat up when her decision puts her family in danger.

Egoyan, whose credits include "Where the Truth Lies" and "The Sweet Hereafter," is directing a script by Erin Cressida.

Ivan Reitman and Tom Pollock, among others, are producing, with Jason Reitman on board as executive producer. Shooting is set for February, according to the trade.

Moore was last seen in "Blindness." She's recently completed "The Private Lives of Pippa Lee." Other upcoming project of hers include "A Single Man" and "Shelter."

As for Neeson, he will soon be seen in Oliver Hirschbiegel's "Five Minutes of Heaven." Seyfried most recently starred in last summer's box office phenomenon "Mamma Mia!"

Colin Firth, Julianne Moore and Matthew Goode are set to star in Tom Ford’s directorial debut “A Single Man.”

According to Variety, the film follows a British college professor who loses his partner of 16 years. I know it’s not much, but that’s all we know at this stage.

Ford and David Scearce adapted Christopher Isherwood’s novel, which details one day in a professor’s life in Los Angeles.

I assume Firth is on board as the lead character. Firth most recently starred in Universal’s hit musical “Mamma Mia!” He recently wrapped filming for “Dorian Gray.”

As for Moore, she was last seen in “Blindness.” She has several projects coming up, including “The Private Lives of Pippa Lee” and “Shelter.”

Goode last starred in “Brideshead Revisited.” He’ll appear in Zack Snyder’s upcoming actioner “Watchmen.”
