Sandra is the boss, says Clooney

Actor George Clooney has joked that his "Gravity" co-star Sandra Bullock is the boss on film sets.

The two stars have been promoting their new project together, "Our Brand Is Crisis".

Clooney is co-producing the comedy-drama, and Bullock stars as "Calamity" Jane Bodine, a political consultant.

"It's nice just to sort of be able to work together. You grow up, you share life experiences, you're mellowing out, you share your new sense of self. We're good at arguing our points of view and never feeling like it got personal," said Bullock.

Clooney's perspective is precisely the same, reports people.com.

It's "really fun," he said, to sit down with someone you know and say, "Well, let's make this movie."

However, "Sandra is boss", he joked.
