From rom-com heartthrob (six-pack always included) to stripper to killer and now prepping to play an HIV patient (as evidenced by his gaunt appearance), Matthew McConaughey came out last night to promote his most recent film, Killer Joe, at a screening hosted by the Cinema Society & Bally at The Tribeca Grand.

McConaughey along with a glowing Camila Alves (who recently announced she's pregnant with her third child) took the red carpet, while a crowd of celebs and movie buffs filled the screening room, followed by an intimate after party at No. 8, a new New York City hotspot.

McConaughey was joined on the red carpet by co-star Gina Gershon (dressed in Bally), as well as the film's director, Academy Award-winner William Friedkin, and Pulitzer & Tony Award winning writer Tracy Letts.

Tracy Letts took a moment to talk to FashionEtc about the inspiration behind the dark story.

"You don't expect that a story will stick with you and grow old with you like a child. I first wrote this when I was 25 years old. I remember seeing the film for the first time and thinking how disturbing it is and being like, 'Oh my god, did I have a fever dream? Where did this come from?'"

"To see the deeply grounded and emotional performances by the actors is very exciting and gratifying for a writer. Just seeing it all come to life is amazing," added Letts.

"There is nothing like this film. Hollywood movies all look the same and you know what's going to happen from the trailers. There is no way you can fathom what is going to happen when you sit down to watch Killer Joe for the first time. Whether you love it or hate it, there is nothing quite like it."

John Stamos, who was joined by Courtney Love, Tony Danza, Russell Simmons, Nicky Hilton, Graham Nash of Crosby, Stills, Nash & Young, Mélanie Laurent, Alan Cumming, Ethan Coen, Roseanne Barr and plenty other famous faces at the after party, told us, "It was scary and exciting. Now I have to go home and take a really long hot shower."
