Matthew McConaughey Calls Dallas Buyers Club Scene 'A Soul Punch'

Appearing on a new episode of Inside the Actors Studio that airs Thursday night (8 p.m. ET) on Bravo, the Oscar nominee discusses a line that will stay with him forever.
"There's a scene in this film where Ron goes, 'I'm dying.' Those two words, 'I'm d-y-i-n-g,' I didn't expect it but it just ... hit me and it floored me," McConaughey tells host James Lipton.
Up for Best Picture at the 2014 Academy Awards on March 2, Dallas Buyers Club follows HIV-positive outlaw Woodroof as he smuggles medicine into Texas and fights pharmaceutical companies peddling a dangerous AIDS treatment.
McConaughey famously shed almost 50 lbs. for the role. Though he has since regained his muscular figure, the actor says he will always empathize with Woodroof's realization that he was approaching death.
"Saying those worlds floored me in a way that I think definitely grounded me since then in a different way than I was before," he says. "Maybe it's my own mortality, but it was a moment personally for me, that I found through Woodroof, that's never gonna leave me."
