In the film industry, bad behavior is hardly a singular occurrence. Actors and filmmakers are doted on, entrusted with millions, and generally fed a sense of entitlement. (They’re also made to suffer 14-16 hour days, sometimes in uncomfortable conditions: monotony can make a jerk of anyone.) Jackson greeting new celebrity with a temper is hardly a news story, and if the film is a hit and Jackson a well-received component, the studios probably won’t much care. But if they feel like they can get Jackson’s charisma in another less-threatening actor, then they will.
It should be noted that Jackson has an uphill battle in getting tenure in the film business: few athletes are able to transition into acting; his other performances in films have been unreviewable. While he may excel as B.A. Baracus, remember that Mr. T did not have a long and prosperous career following his stint on the original TV series. For Jackson, range may be a problem outside of the ring, too.
