Brad Pitt sparks fight with Angelina Jolie over love for guns
In the new movie, the 48-year-old actor is seen wreaking havoc with a variety of firearms.
And Pitt is now so keen on guns that he has become a regular at a private Los Angeles firing range, where he uses a Mossberg 500 "Cruiser" shotgun exactly like the one he has in the film, the Daily Star reported.
The Mossberg is so highly regarded as a tactical weapon that the M590 model is used by the US Marines' Fleet Anti-terrorism Security Team in combat.
A source close to Pitt said: "He's really hooked."
But Jolie is said to be "furious and frightened" over his newfound love of weapons.
"She refuses to let him keep them in any of their homes," a friend said.
"And she has banned Brad from setting up a practice range in the grounds of their Hollywood Hills mansion," the friend said.
