Jake Gyllenhaal & Rachel McAdams At Afterparty Following Southpaw Screening — 9 Photos Of A-Listers Celebrating Boxing Film Out Today!

Jake Gyllenhaal and Rachel McAdams were out in Los Angeles Monday night at an afterparty following a screening of their highly-anticipated movie Southpaw.

The cast of the highly-anticipated film — 50 Cent, Gyllenhaal, Oona Laurence, McAdams, Miguel Gomez and Terry Claybon — pose for a group shot.

Gyllenhaal — posed here with the rapper-actor and Gomez — trained at Floyd Mayweather, Jr.'s Atlanta-based boxing center in preparation for his role.

The bearded hunk plays Billy "The Great" Hope in the movie, adding another vivid role to his repertoire, which includes films such as Brokeback Mountain, Jarhead and End of Watch.

Canadian beauty McAdams looked stunning at the event, at Cecconi's West Hollywood.

Gyllenhaal explained the complicated aspects of filming the boxing movie in a chat with The Guardian: “Even when you’re only filming a fight, even when it’s a movie, in the ring you feel totally naked ... it’s a strange thing, 700 extras watching.”

Gyllenhaal said that when he absorbed punches while filing the movie, his “first thought was always, ‘Someone better have got a good f**king angle on that’ -- that’s an actor.”

McAdams, speaking with ET, said she finds rumors that she might be dating True Detective co-star Taylor Kitsch “weird.”

“I guess you just have to laugh at it at a certain point,” McAdams said of online speculation on her love life, dubbing it a “weird, weird, bizarre, surreal side” of show business.

Southpaw opens in theaters nationwide July 24.
