Doctors have said there “is no further hope” for actor Tom Sizemore, and recommended his family make an end-of-life-decision, his manager has said.

The 61-year-old has been in intensive care, in a critical condition, since suffering a brain aneurysm at around 2am on Saturday, 18 February while at his Los Angeles home. He is understood to be in a coma.

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. The film won five Academy Awards.

He also appeared in Strange Days, as well as 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.

His manager, Charles Lago, said in a statement: “Today, doctors informed his family that there is no further hope and have recommended [an] end-of-life decision.

“The family is now deciding end-of-life matters and a further statement will be issued on Wednesday.”

He said on Monday that Sizemore’s family were asking for privacy, adding: “They wish to thank everyone for the hundreds of messages of support, and prayers that have been received.

“This has been a difficult time for them.”

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.
