Actor Tom Sizemore remains in critical condition at a Los Angeles-area intensive care unit after suffering a brain aneurysm at his home on Saturday.

Sizemore, 61, collapsed and was found unconscious around 2 a.m., his manager Charles Lago told KTLA 5 News. 

Lago said someone in the home called 911 and paramedics rushed Sizemore to a hospital.

“He’s in the ICU and not responding to treatment,” Lago explained.

The manager went on to reveal that Sizemore will be getting “major MRI work done” on Monday and they’ll be awaiting those updates.

Sizemore has starred in blockbusters including “Saving Private Ryan,” “Natural Born Killers,” “Heat” and “Blackhawk Down.”

His acting career, however, has been marred by legal issues and challenges with substance abuse.
