'Hail, Caesar!' Stars George Clooney, Channing Tatum on Coen Brothers

As a Coen Brothers film alum, George Clooney already knew what he was getting into when he signed on for “Hail, Caesar!”

“When you get their screenplay, basically that’s the screenplay you shoot,” Clooney explains. “They shoot, literally, only the shots they use.” He adds, “They’ve already edited the film in their heads. It’s incredible confidence and it’s panned out for them because they make really wonderful films.”

Meanwhile, it was a freshman experience for Clooney’s costar Channing Tatum, who says he didn’t hesitate to join the star-studded cast.

“I didn’t even need to read it,” he says of the comedy. “They are master filmmakers. Anybody in their right mind that is not a complete moron says ‘yes.'”

In “Hail, Caesar!” Tatum plays Burt Gurney, a sailor uniform-loving singer-dancer-actor a la Gene Kelly.

The picture follows 1950s Capital Pictures executive and studio fixer Eddie Mannix, played by Josh Brolin, who must resolve a whopper of a problem when his studio’s biggest star Baird Whitlock, played by George Clooney, goes missing. Also featuring Scarlett Johansson, Tilda Swinton, Jonah Hill and more, “Hail, Caesar!” opens Friday. Watch the trailer below.
