"New Orleans nearly killed us, let's be honest," Courtney explained. "It's a town where the bars are open 24/7. You got five dudes, you know, coming from all corners of the globe who happened to be like straight savages themselves. We're all there [as] professionals, you know, for the work, all about the work. But what the work demanded of us was that, you know, we come together and we break bread and we get a little rambunctious and we kind of take the piss out of each other."
"New Orleans set quite the scene," he added. "I think we were all lucky to escape with our lives."
Like Courtney, Wolff and Castro both said partying during Mardi Gras was a true bonding experience.
"I grew up going to New Orleans every summer and every Thanksgiving because my dad's side of the family is from there," Wolff said. "So going there was like going back home, but Jai and I especially immediately bonded up and the rest of the guys -- it was a family affair."
"After [Mardi Gras] it's just like, you know, we were tight," Castro added. "We were all just brothers after that."
One moment that particularly brought them together? Seeing co-star Finn Wittrock dance.
"It's just very, very seductive to me," Castro joked of Wittrock's dance moves. "I find [them] very sultry."
Since the preface of the film involves a prison break, TooFab asked the cast who they would want on their prison break dream team. See who the guys picked in the video, above.
"Semper Fi" follows Cal (Courtney), a police officer who serves in the Marine Corps Reserves, facing an ethical dilemma when his half-brother Oyster (Wolff) lands in jail for accidentally killing a man. Cal and his friends then hatch a "no holds barred" plan to break Oyster out of prison.
Leighton Meester, who also stars in the film, told TooFab what drew her to the project and what it was like being one of the only females on a set full of -- as Courtney said -- "rambunctious" men.
Check out our interview with Meester in the clip, below.
"Semper Fi" will be released in theaters, digital and on-demand October 4.
