The American actor Tom Sizemore, best known for his roles in the films Saving Private Ryan and Heat, has died at the age of 61.
Sizemore had been placed into a coma in intensive care since suffering a brain aneurysm and collapsing at his Los Angeles home on 18 February.
He died in his sleep on Friday at a hospital in Burbank, California, his manager Charles Lago confirmed to the AP news agency.
Shortly before his death, the actor's family announced that they were "now deciding end-of-life matters".
Sizemore's first major appearance was in the 1989 Oliver Stone film Born on the Fourth of July.
That performance opened doors in Hollywood and he carved out a niche playing the quintessential hardman, from gangsters to bodyguards and soldiers.
He secured supporting roles in films such as Point Break, True Romance and Natural Born Killers.
His portrayal of professional thief Michael Cheritto in the 1995 heist film Heat, written and directed by Michael Mann and starring Al Pacino and Robert De Niro, won him plaudits.
He also received acclaim for his performance opposite Tom Hanks in Steven Spielberg's 1998 WWII epic Saving Private Ryan.
Sizemore made a memorable contribution to the popular video game Grand Theft Auto: Vice City, voicing mob boss Sonny Forelli.
Among his many other credits were the series Cobra Kai, Twin Peaks and Hawaii Five-O, and the films Black Hawk Down, Pearl Harbor and Devil in a Blue Dress.
The Detroit-born actor had a history of drug addiction. He wrote in his autobiography about his heavy use of heroin and crystal meth. He was once checked into rehab by De Niro.
He was married to the actress Maeve Quinlan, known for her role in the US soap opera The Bold and the Beautiful, between 1996 and 1999.
In 2003, he was convicted of domestic violence charges against his former girlfriend Heidi Fleiss. Sizemore was ordered to complete a drug rehabilitation programme before beginning a jail term.
He pleaded no contest to using methamphetamine outside a motel in 2006 and was arrested in Los Angeles in 2009 for suspected battery of a former spouse. He was arrested again in 2011 for the same offence. In 2017, he pleaded no contest to more domestic violence charges.
In 2018, an actress filed a lawsuit against Sizemore, claiming he allegedly groped her when she was an 11-year-old during production on the 2005 film Born Killers.
Sizemore strongly denied the allegation and the suit was dismissed.
He is survived by his 17-year-old twin sons, Jayden and Jagger, and his brother Paul, all of whom were reportedly by his side when he died.
