Mark Wahlberg plays a Navy Seal on a mission in Afghanistan for his latest film, "Lone Survivor," but the actor made it abundantly clear that what he did to prepare for his role was nothing compared to what a real soldier faces.

During a Q&A after the Tuesday screening of the film about the real-life 2005 Navy Seal mission to capture or kill a notorious Taliban leader, Wahlberg, who's famous for his bluntness, went off on a five-minute rant when asked about his rigorous training for the shoot.

"For actors to sit there and talk about, 'Oh, I went to SEAL training,' I don't give a f*** what you did. You don't do what these guys did," the actor said, according to Entertainment Weekly. "For somebody to sit there and say, 'My job was as difficult as being in the military?' How f****** dare you, while you sit in a makeup chair for two hours."

"I don't give a s*** if you get your a** busted," the actor ranted. "You get to go home at the end of the day. You get to go to your hotel room."

Wahlberg, who sat on stage next to director Peter Berg and Petty Officer Marcus Luttrell, on whose book "Lone Survivor" the film is based, complimented the pair on helping create the film's realistic depiction of the failed mission.

"I love Marcus for what he's done and I'm a very lucky guy to do what I do and I'm proud to have been part of it, but it's just so much bigger than what I do," Wahlberg said, according to Entertainment Weekly.

He said Luttrell and other Navy Seals consulting on the film would stop him and the other actors if something didn't ring true. "I was really proud to be a part of that," Wahlberg said.

Then he wrapped his impromptu monologue by saying simply, "I'm sorry for losing my s***. Don't ask any more questions tonight."

When Berg tried to lighten the mood by telling the audience it had been a long night, Wahlberg responded, "No, it's just getting … started. I'm going to find my … second wind and we're going to celebrate this … movie. But don't ask me any more questions."
