The late '90s weren't kind to actor Martin Lawrence.
In 1995, Martin was hospitalized after an angry, uncontrollable outburst on the set of the movie "The Thin Line between Love and Hate," his directorial debut. In 1996, his "Martin" co-star Tisha Campbell accused him of sexual harassment and battery, verbal abuse and other threats, before she quit the show [source: Turner Classic Movies]. That same year, Martin's wife slapped him with a restraining order after accusing him of physical abuse (and they divorced in 1997).
Right around this same time, Martin was arrested while attempting to board a plane while carrying a 9mm Beretta. He got into fights. He was found screaming at tourists -- while carrying a gun -- in the middle of Ventura Boulevard in Los Angeles.
After the incident on Ventura Boulevard, Martin was hospitalized for exhaustion and dehydration. Others, including his ex-wife, cite his chronic marijuana and alcohol use (and possibly psychotropic medications) for his erratic behavior. Still others point to mental illness such as bipolar disorder. Although Martin admits he did smoke marijuana and has been treated for depression in the past, it was his three-day coma caused by heat exhaustion while jogging in heavyweight clothing that the actor cites as his reason for cleaning up his act.
