Taylor Kitsch is in talks to join Ryan Murphy's TV drama The Normal Heart.
The John Carter star is tipped to play gay investment banker Bruce Niles, who becomes an outspoken Aids activist in the HBO adaptation of the Tony Award-winning play of the same name by the Glee creator, reported Deadline.
Written by Larry Kramer, The Normal Heart focuses on the HIV-Aids crisis in New York City in the early 1980s.
Julia Roberts has already been cast as Dr Emma Brookner, a survivor of childhood polio who treats several of the earliest victims of HIV-Aids.
Mark Ruffalo is on board for the role of Ned Weeks, who watches first-hand as the disease claims the lives of many in the gay community and starts looking for answers, while Magic Mike actor Matt Bomer will play his lover and reporter Felix Turner.
The Big Bang Theory's Jim Parsons will reprise his role as gay activist Tommy Boatwright, which he previously took in the play's Broadway revival in 2011.
Production on the TV movie is expected to begin later this year in New York for a 2014 debut.
Taylor, who starred in Oliver Stone's Savages, Battleship and John Carter, will next reunite with director Peter Berg for Lone Survivor. He's also attached to a remake of Jean-Francois Pouliot's French-Canadian The Grand Seduction and is in talks to star in the upcoming big-screen adaptation of Need For Speed.
