Directors Bryan Singer and Gus Van Sant are both trying to make a film based on the life of Harvey Milk, the San Francisco supervisor and first openly gay elected official in the U.S., who was assassinated along with Mayor George Moscone by Supervisor Daniel White.

Singer was brought in two years ago on The Mayor of Castro Street for Warner Independent Pictures, the movie based on the book by Randy Shilts; through Participant Productions, Chris McQuarrie is set to write the final draft, says Variety.

Van Sant has also attached himself to an untitled Milk script by Dustin Lance Black. Adding to the intrigue is that fact that Van Sant was once set to direct Castro Street and even wrote a draft of the script years ago for Warners.
