Slashfilm now has the first on-set photos from Gus Van Sant's Harvey Milk biopic, Milk. As we all know, Bryan Singer's competing Milk film, The Mayor of Castor Street, has been parked in development hell. Now it looks like Van Sant's film will be the first Hollywood life-story of the legendary mayor of San Francisco, so get ready for a little stroll down memory lane since most of these photos are of the local spots in the area being given a 1970's makeover.

For those of you not familiar with Milk's legacy, he was, "an American politician and gay rights activist, was the first openly gay city supervisor of San Francisco, California, and therefore, according to Time magazine, 'the first openly gay man elected to any substantial political office in the history of the planet.'" The perpetually dour Sean Penn will play Milk, and most gossip had Matt Damon in the role of Milk's murderer and co-worker, Dan White. Now it's looking like Josh Brolin will step in. Other cast members include Emile Hirsch, James Franco, and Diego Luna

While most of the focus had been on whether Penn could pull off the congenial and upbeat Milk, I have to admit I'm a little nervous on the directing end of things as well. As much as I respect Van Sant, I wonder whether he is willing to make a more 'conventional' biopic. It might be the only way to introduce as many people as possible to this invaluable figure in gay rights, rather than alienating them with something a little more along the lines of Last Days. Milk is set to open in theaters later this year.
