Producer Jon Peters wants to remind us that Bryan Singer is actively moving forward on the "Superman Returns" sequel. Just a bit slowly is all.
Here’s what producer Jon Peters had to say: "Bryan Singer is working on the story (for the sequel to SUPERMAN RETURNS), and hopefully, that will be a script by the end of the year. And hopefully, we’ll be in preproduction by, say, January or February of next year."
So now you know. The producer also goes on to say that Mr. Singer is "brilliant," "sweet," and "like one of my kids." Which is really nice.
