HBO's Michael Lombardo said in a statement: ''We are so proud to be involved with this monumental project. Ryan has assembled an extraordinary cast to bring Larry Kramer's landmark theatrical achievement to the screen for the first time, and we couldn't be more thrilled to bring this important film to HBO.''

Mark Ruffalo and Matt Bomer will co-star in the drama which is set to air in 2014 with Mark playing Ned Weeks, ''who witnesses first-hand the mysterious disease that has begun to claim the lives of many in his gay community and starts to seek answers.'' ''

Matt will play Felix Turner, a reporter who becomes Ned's lover.
