Trivia: The studio attempted a rather peculiar marketing gimmick. They attempted to have quarters printed that featured the image of the Silver Surfer. The idea was eventually vetoed.
Trivia: Jessica Alba's blonde hair in this film is actually a wig. She had dyed her hair blonde for the first film, but it unfortunately damaged her hair, and she didn't want that to happen again.
Answer: I would assume that the director wanted to make her appear closer to the comic book Sue...this would also explain how blonde her hair is in this film.
