Actor Bill Paxton has died at the age of 61 because of complications following a heart surgery, his family said.
The Titanic and Aliens star passed away on Saturday, after a heart surgery had complications post-op and he suffered a fatal stroke, according to TMZ.
The talented actor was in a host of Hollywood hits, including Twister, Apollo 13 and Edge of Tomorrow, had an Emmy for Hatfields and McCoys, and was in the Golden Globe-nominated HBO series Big Love.
Celebrities such as William Shatner, Rob Lowe, Zach Braff and several more have taken to social media to mourn the loss of their friend and colleague.
Paxton was set to appear alongside Tom Hanks later this year in The Circle, who said in a tweet: 'Bill Paxton was, simply, a wonderful man. A wonderful man.'
Director Doug Liman, who worked with Paxton in Edge of Tomorrow, said the actor was worried about his upcoming surgery, the NY Daily News reported.
Liman said Paxton wrote him an email that said: 'Thanks for the good wishes. It will help me face this ordeal. Don't worry "Sgt Farrell" will be ready to report for duty.'
The actor was expected to work with the director again in a sequel of the original 2014 action film as character Master Sergeant Farell.
Liman added to the NY Daily News: 'Even facing major surgery, his optimism for the future was infectious.
'He was talking about the future, things we hoped to do together.'
