Penn and Damon to play Milk and White?

Of course, nothing's a done deal in Hollywood until the projector starts rolling with film in it, but there's news coming out of Toronto that one of two long-planned Harvey Milk biopics has its leads in place, in the forms of equally impressive Sean Penn and Matt Damon.

For gay director Gus Van Sant's planned biopic, Penn is attached to play assassinated gay San Francisco supervisor Milk, and Damon to play his assassin, fellow supervisor Dan White (who killed both Milk and Mayor George Moscone in 1978 and was convicted merely of voluntary manslaughter as a result).

Milk was the first openly gay city supervisor of San Fran. And interestingly, this is the first time Penn (who has been acting for what seems like 50 years or so) will play a card-carrying gay character in a movie. Damon's participation is dependent on scheduling (he likely has The Bourne Redundancy and The Bourne Ice Capades to film later this year), but he and Van Sant have made magic together in the past and it would be great to see them together on this one.

Remember, Bryan Singer's The Mayor of Castro Street project (based on Randy Shilts' book) is still up in the air as well. Still no word on any development or casting news on that one.

Given this announcement, any suggestions for the other film's leads?
