Deadfall, Olivie Wilde, Charlie Hunnam

Magnolia Pictures

Olivia Wilde knows what it's like to get down and dirty with Christian Grey.

She and newly-minted Fifty Shades of Grey star Charlie Hunnam shared some steamy scenes in last year's Deadfall.

"I'd like to think that our love scenes sort of prepared him for this experience," Wilde told me with a very big laugh yesterday while promoting her new flick Rush at the Toronto Film Festival.

And critics of Hunnam's casting, step aside! Wilde's got his back.

"Audiences should just shut up and wait to be surprised, wait to be delighted," she said.

She's also not surprised that Hunnam took the role. "Charlie is already departing so much from himself to play what he plays in Sons of Anarchy," Wilde said. "Charlie is a kid from Newcastle, England and he plays this biker dude who's bad ass—that makes me think he could do anything."

Has Wilde read Fifty Shades? Not yet. "Someone gave me an extremely weathered copy of it, which was hilarious," she said. "They were like, 'Read this, I'm done with it.' I was like, 'Oh, gosh—these pages are, like, sticky.'"

And speaking of hot men in Wilde's life—in Rush she plays Suzy Miller, the real-life first wife of the late Formula One champion James Hunt.

Hunt happens to be played by hunky Aussie Chris Hemsworth. "He's just so ugly," Wilde cracked. "I feel so bad for him. Blech!"

The Ron Howard-directed Rush tells the story of the legendary feud of the 1970s between Hunt and rival driver Niki Lauda (Daniel Brühl).

"What sets Chris apart is he's really very grateful for his position in this business," Wilde said. "He worked very hard to get here and he appreciates it."
