They keep telling us a Superman Returns sequel is right around the corner, but at the same time director Bryan Singer keeps moving ahead with a different gig. Though he's been attached to The Mayor of Castro Street for two years now, it appears development on the pic has picked up steam after it was revealed that Gus Van Sant had begun work on a similar project. Based on the book by Randy Shilts, Castro Street will tell the real-life story of Harvey Milk, the first openly gay elected official in the U.S. Milk's life was tragically cut short when he -- and San Francisco Mayor George Moscone -- were assassinated by Supervisor Daniel White in 1978.

Variety tells us that Van Sant has attached himself to another Milk-related script; this one was written by Dustin Lance Black (Big Love). That project is set to be shopped around town early next week. At the same time, Warner Independent Prods. is close to a deal with Participant Prods. to co-finance Singer's Castro Street, and Chris McQuarrie (who teamed with Singer on The Usual Suspects and the recent WWII thriller, Valkyrie) will pen the final draft. We all know what happened with the whole "Capote Incident" -- how two pics, Capote and Infamous, hit theaters roughly one year apart with the former gaining a lot more recognition than the latter. Since The Mayor of Castro Street has been in development for 15 years, I assume Singer and Co. will fight tooth and nail to get their Milk story in theaters faster than Van Sant can say, "Got Milk?"

But what about Superman: The Man of Steel? We already know that Singer will helm Valkyrie (with Tom Cruise attached to star) before the Supes sequel (currently scheduled to hit theaters in 2009). Is it possible for him to fit in another film, and still be able to deliver the superhero flick on time? Is Bryan Singer faster than a speeding bullet? I guess we soon shall see ...
