Clint Eastwood, 92, is soon set to start filming his final film, a thriller titled Juror No 2, which will see him share the screen with Nicholas Hoult and Toni Collette.
However, observers could not help but notice that the Gran Torino star has not been seen in public in more than 450 days.
One source claimed Hollywood insiders have been “worried” about the big screen icon despite his “great health” and vitality.
They said: “Clint has always enjoyed great health and been vital and active despite his advancing age, but the fact that he hasn’t been around as much lately has a lot of people in Hollywood worried about him.
“It’s hard to imagine him in anything other than fine form but Father Time catches up to all of us,” the source claimed to Radar Online.
Express.co.uk has contacted Clint’s representatives for comment.
Clint has had an incredible Hollywood career spanning 70 years, which saw him play iconic roles in films including The Man With No Name and Dirty Harry.
In more recent decades, he’s proven himself as a talented director too, and was behind the likes of Unforgiven and Gran Torino, but the star, who turns 93 later this month, has been pretty quiet since starring in Cry Macho two years ago.
The actor previously looked back on his career and shared his reasons for turning two of the biggest roles of all time down.
He said: “I can remember – and this was many years ago – when [Warner Bros. President] Frank Wells came to me about doing Superman.
“So it could have happened. This was when they first started to think about making it.
“I was like, ‘Superman? Nah, nah, that’s not for me.’ Not that there’s anything wrong with it. It’s for somebody, but not me.”
However, the Hollywood icon had no issue with the genre and happily revealed his own love of comics, adding that his favourite character is Marvel’s Namor: “The Sub-Mariner, that’s the one I always liked. I had all of those comics when I was a kid.”
When Superman eventually hit the big screen with Christopher Reeve, Eastwood was enjoying major success away from his cowboys and cops projects with the light-hearted Every Which Way But Loose (alongside orangutan Clyde).
But, at the time and later, his main reservation (apart from the tights) had been that any such role risked overshadowing an entire career.
He said: “That was part of the consideration, a big part. Look at Reeve, he was excellent. That was a big factor. You get a role like that, and it locks you in a bit.
“True, I had the western genre and the Dirty Harry role, but everybody made westerns and did cop movies; they didn’t seem as bad,” Clint added to the LA Times.
