An all-star cast (including Christina Ricci, Dylan Baker, Peter Fonda, Jeremy Davies, Janeane Garofalo, Laura Linney, Steve Buscemi and Amy Madigan) delivers a compelling performance based on a theatrical portrayal of reactions to the Matthew Shepard story, a 1998 murder that took place in Laramie, Wyo., and became a lightning rod for rallies against homophobia and hate crimes. Moisés Kaufman writes and directs, based on his own stage play.
