Little Nicky (2000)

Nicky is just a guy who'd rather play heavy metal music in his bedroom sanctuary than climb the corporate ladder in his family's thriving business. Ruthless older brothers Adrian and Cassius are much more ambitious. When their aging father decides to postpone his retirement, the sinister duo defects, leaving home to set up shop in a new location -- New York City. This is about to become a big problem for the "Big Apple." Nicky's dad is the Devil, himself. Adrian and Cassius evade the Gatekeeper's efforts to stop them and make a hasty exit from Hades. As a result, the gates of hell freeze over and with no more evil souls able to enter, their dad starts to fall apart-- literally! It's up to Little Nicky to save him by finding his rotten brothers and bringing them home before his dad wastes away.
