A source for the Aintitcool.com folks is claming to know about a buttload of big name actors joining Superman Returns.  If this is true this is going to be a giant film. Click over for the goods.

Here's the best part of the Aintitcool post:

"I have some exclusive casting news on Superman Returns. Kal Penn (Harold & Kumar Go To White Castle, Van Wilder) has indeed signed on, as a earring wearing, tattooed punk that serves as Luthor's right hand man.

Famke Janssen's (X-Men 1 & 2, Goldeneye) meeting with director Bryan Singer down under was for Superman Returns, and she has snagged the role of Lora, the birth mother of The Man Of Steel, while Daniel Day-Lewis (Gangs Of New York, The Last Of The Mohicans) has gotten the role of his birth father, Jor-El.

As for the other villians, Jude Law (Cold Mountain, Gattaca) has finally signed on as General Zod, and Kevin Bacon (Mystic River, Apollo 13) has signed as John Corbin.

Finally, Barry Pepper (Saving Private Ryan, The Green Mile) has gotten the role of a reporter at the Daily Planet, who becomes Clarke's rival after his return. Expect WB to make these casting bits official in about a week."

Jeez. We'll see how much of it comes true.
