"The Marine" is noteworthy for several reasons. It marked the first lead performance by John Cena in a film project. It also partnered Cena with Robert Patrick, and the two would reunite years later on "Peacemaker" with Patrick portraying Christopher Smith's father, Auggie. But as Cena revealed in an interview with GQ, that opportunity wouldn't have happened if Steve Austin hadn't dropped out shortly before filming was set to start.
As Cena described, "[The Marine] was originally a role that was written for Steve Austin, and two weeks before shooting, Steve backed out for whatever reason. That's a conversation with him. But Vince [McMahon] said, 'Hey, I gotta send you to Australia.' I said, 'Okay, what am I doing?' And he said, 'Well, you're gonna be in a movie.' 'Okay, when?' 'I gotta send you in 10 days.' But I pretty much left a small meeting in his office and packed my bags and went to be in the movies, which I knew nothing about."
"The Marine" wasn't exactly a critical darling, but Cena goes on to explain how he's proud of the work he did on the film: "People talk to me about it to this day. So it's great that, you know, you do something that people remember and maybe it affects their life, which is really cool." It's safe to say working on "The Marine" was a blessing in disguise, as it showed Cena could lead a project, paving the way for works like "The Suicide Squad" and "Peacemaker," where he gets to combine his action chops with his comedic sensibilities.
