Actress circling female lead.

Jennifer Garner (‘Butter,’ ‘The Odd Life of Timothy Green’) has entered into talks to join Matthew McConaughey and Gael Garcia Bernal in ‘Dallas Buyers Club,’ says Deadline.

Long-in-development, ‘Dallas Buyers Club’ is the true story of Ron Woodroof (McConaughey), a tough Texas electrician who was diagnosed with AIDS in 1986 and given six months to live. Frustrated with the lack of available medical options and unwilling to accept a death sentence, Woodroof found a lifeline using alternative drugs and created a lucrative smuggling business that made those drugs available to AIDS patients. Woodroof’s actions put him on a collision course with the U.S. Food and Drug Administration, which was bent on keeping the drugs out of the country.

Garner is said to be circling the role of Woodroof’s physician, Dr. Eve Saks, a part recently linked to Hilary Swank.

Actor and 30 Seconds to Mars frontman Jared Leto has also boarded the drama, and will portray Rayon, a fellow AIDS patient Woodruff befriends at the hospital.

Production on the Jean-Marc Vallee-directed drama is set to begin in New Orleans in the coming weeks with a script by Craig Borten and Melisa Wallack.
