Following his sudden and tragic passing last month at the age of 61, the late Bill Paxton’s cause of death has been officially listed as having suffered a stroke that occurred 11 days after heart surgery.

The actor, famous for his roles in Aliens, Twister and True Lies, underwent an operation to fix an aortic aneurysm and replace his bicuspid aortic valve on Valentine’s Day, according to his death certificate which was published on Monday (March 6th) by TMZ.

However, complications arose from the difficult surgery and, 11 days later on February 25th, Paxton suffered a stroke that proved to be fatal.

“A loving husband and father, Bill began his career in Hollywood working on films in the art department and went on to have an illustrious career spanning four decades as a beloved and prolific actor and filmmaker. Bill’s passion for the arts was felt by all who knew him, and his warmth and tireless energy were undeniable. We ask to please respect the family’s wish for privacy as they mourn the loss of their adored husband and father.”

Born in 1955 in Texas, Paxton began his Hollywood career in the 1970s. While he was rarely a lead star, he held down memorable roles in the likes of Titanic, The Terminator, Twister and Edge of Tomorrow.

However, arguably his most well-known character was that of the eternally jumpy and pessimistic Private Hudson in sci-fi sequel Aliens, whose utterance “That’s it! Game over, man!” has been immortalised in internet memes and gifs.

He married twice, and had two children, James and Lydia, with his second wife Louise Newbury.
