Made for a budget of $33 million, according to BoxOffice.com, "The Imitation Game" has grossed more than $155 million worldwide since its November release.

It earned Oscar nods for Cumberbatch, Knightley, director Morten Tyldum and the coveted best picture prize, where it will contend against frontrunners "Birdman" and "Boyhood."

Tyldum, the Norwegian director of 2011's "Headhunters," said while Scandinavian filmmakers such as himself hone their talents on American genre films, they bring a fresh aesthetic for underdogs such as Turing to Hollywood films.

"We're very skeptical of people who are too perfect. We like flawed people," Tyldum said. "The more shaded, flawed characters that are struggling, I think there's something very relatable about that."

Much of the film focuses on Cumberbatch's portrayal of Turing's nuances, vulnerabilities and strengths as an outcast among his peers.

Both Tyldum and Moore, who won best adapted screenplay at Saturday's Writers Guild Awards, faced initial concerns from film financiers that a film about an unknown historical figure who commits suicide would be marketable to audiences.

"I love when people say 'Imitation Game' is such a crowd pleaser," Tyldum said. "Yes, it's a crowd pleaser but the guy kills himself. We've achieved something, it's a beautiful challenge."

Moore said he relished the challenge of making "an unmakeable project."

"The whole goal of the film was to bring Alan Turing's story to a crowd that wouldn't otherwise have been exposed to his life and his work and his person."
