Hollywood star Gerard Butler admits being a control freak. Butler was serving as a producer for the film, Greenland, when he enjoyed the chance to have a more hands-on role in the project.

"I'm a control freak! As an actor, when you're coming up, you beg for roles, and you're lucky to get one and then you suddenly find yourself in a position where movies are being made, because you're involved," Butler told Total Film magazine, femalefirst.co.uk reported.
