The film, releasing this Friday in the US, stars Cruise as a hard-boiled former military cop trying to prove that an alleged sniper was framed.
The studio wouldn't officially say what the changes are, but a source confirmed that a scene of Cruise's character firing off a semi-automatic weapon is being cut from promotional spots, the Hollywood Reporter said.
'Jack Reacher' reportedly opens with sniper fire, isn't the only Christmas movie that has violence.
The planned Hollywood premiere of Quentin Tarantino's much-anticipated film "Django Unchained" has also been cancelled by the Weinstein Company.
