Son of the Mask (2005)

A decade after the legendary Mask of Loki wreaked havoc on the life of an unsuspecting adult, the magical mask finds its way into the possession of a child in the family comedy Son of the Mask. When cartoonist Tim Avery's (Jamie Kennedy) new son is born with the Mask's spectacular powers - to the dismay of the family's jealous dog - it turns the household upside down and launches a kid versus canine battle for control of the Mask. But unbeknownst to them all, Loki has come looking for his mask and is willing to do whatever it takes to get it back.
