Alan Cumming

For Halloween 2002 in Vancouver, Cumming and his X2: एक्स-में यूनाइटेड (2003) costar, Ian McKellen, dressed as their characters Fegan Floop (from "Spy Kids") and Gandalf (from the Lord of the Rings trilogy) respectively. 'He carved me this great Nightcrawler pumpkin and helped answer the door so there were Gandalf and Floop handing out candies,' says Cumming.
