There's a "Silver Surfer" movie in the works but it'll be written by prolific storyteller J. Michael Straczynski.
JMS told a little bit about his plan for the "Surfer"'s second film entry.
"It picks up right where the FF movie left off and it's designed to answer the questions that were asked in the movie but really weren't dealt with there, which [were]: Where did he come from, why did he become the Surfer and what is he doing here now?"
When asked about the handling of Galactus in
Rise of the Silver Surfer, Straczynksi replied, "I thought it was all they could do in the course of that movie, but in the second movie, you will see more of him." He went on to say, "You don't want to sort of blow out something that big and massive for one quick shot in the first movie… Where you're showing the origin of the Surfer, that's where you do it; that's where you blow it out."
No comment from anyone yet on whether those rumours about Alex Proyas ("I, Robot") being attached to direct it are true.
