Actor Tom Sizemore is in a critical condition after suffering a brain aneurysm.
The 61-year-old suffered the aneurysm at around 2am on Saturday while at his Los Angeles home, his manager Charles Lago said.
The actor is in intensive care in hospital, with Mr Lago describing the situation as “wait and see”.
Sizemore is best known for his roles as the sergeant at Tom Hanks’ side in the 1998 Second World War epic Saving Private Ryan, and as commander of an army ranger battalion in the 2001 film Black Hawk Down.
He also appeared in 1995 crime drama Heat, and was nominated for a Golden Globe award in 2000 for best actor in a miniseries or film made for TV for his role in Witness Protection.
Sizemore has struggled with drug addiction during his acting career, having been arrested a number of times for driving under the influence and drug possession.
In 2003, he was convicted of domestic violence against his girlfriend Heidi Fleiss and three years later he pleaded no contest to using methamphetamine outside a motel.
He was arrested in 2009 and in 2011 for suspected battery of a former spouse.
