"We are exploring it," Moonves said at a PricewaterhouseCoopers media event in New York. "We're not looking to do 'Superman."'
Moonves did not provide details on how CBS would set up a movie venture, whether through acquisition or building up its own properties.

"We could get in in a small way, doing six to eight movies a year in a risk-free way," Moonves said.
