Jon Hamm, James Franco compare Prop 8 fight to 'Howl' ban

"Mad Men's" Jon Hamm and James Franco star in the upcoming Allen Ginsberg biopic "Howl," one of the hotly anticipated films at the 2010 Sundance Film Festival. 

At a Sundance press conference, Hamm and Franco likened that long-ago obscenity trial and fight for Ginsberg's Beat Generation poem "Howl" to be published to today's ongoing struggle for equality and the passage of Proposition 8, banning the right of homosexuals to marry in the state of California.
