The film industry is honoring Tom Sizemore after learning the actor died from a brain aneurysm at the age of 61.

Sizemore, best known for his role as Mike Horvath in "Saving Private Ryan," died peacefully in his sleep on Friday at St. Joseph’s Hospital Burbank surrounded by his brother Paul and 17-year-old twin boys Jayden and Jagger, Sizemore's representative Charles Lago said in a statement to Fox News Digital.

The actor had collapsed in his Los Angeles home on Feb. 18 and was rushed to the hospital. He was determined to be suffering from a brain aneurysm that resulted from a stroke. He has since remained in critical condition and received intensive care and had not regained conciseness.

On Monday, Lago said, "Doctors informed his family that there is no further hope and have recommended end-of-life decision," adding that the family is "now deciding end-of-life matters."
