Tom Hanks’s appearance on Saturday Night Live this weekend sparked fresh concerns for his health.

The actor, 68, turned out to support host Martin Short along with a slew of guest stars including Scarlett Johansson, Paul Rudd, and John Mulaney.

During the show’s recurring Five-Timers Club segment, which inducted the Only Murders In The Building star, fans noted the Forest Gump icon’s trembling hands.

One fan commented under a promotional post on SNL’s official Instagram account, ‘Is Tom Hanks’ hand shaking?’

A user named Lara joined the thread to add, ‘I also noticed it!!! And now I am concerned.’

DailyMail.com has reached out to Hanks’ representative for comment.

Another concerned fan mentioned that ‘He was on The Graham Norton show a while back and I noticed it there too…’

One person reasoned, ‘Considering he’s almost 70! Yeah older people hands tends to shake a little.’

It’s not the first time fans have expressed worry over the Hollywood leading man’s shaky hands.

In June of 2022, the beloved actor’s shaking led one doctor to tell DailyMail.com it could be an early sign of Parkinson’s.

Hanks appeared unable to control his trembling right hand while holding a microphone and speaking as he promoted Baz Luhrmann’s Elvis movie.

Hanks tried to control the shaking by placing his left hand at the bottom of the microphone, below his right. He also briefly switched hands.

Dr. Stuart Fischer, a Yale University graduate with four years’ experience in emergency medicine, who is now the medical director of two nursing homes in New York City, said the Australia footage suggested the degenerative disease.

‘Parkinson’s would be uppermost in most physicians minds,’ he told DailyMail.com, after viewing the footage.

‘This trembling hand can be an early sign of the disease.

‘One would think he would be on the path to a neurologists office now if not already.

‘It could be weeks, months or years before it progresses. It could be like with the famous conductor James Levine, it did take many years for a leg tremor to evolve into a bodily manifestation.’

He said the shaking could be tremors, but given Hanks’ age it was unlikely.

‘The other condition it could be is an essential tremor, but this usually occurs at a younger age — although it can be worsened by anxiety and stress,’ he said. ‘It usually affects people in their 20s and 30s.’

Asked if it could be linked to Hanks’ diabetes, he said: ‘No link to type 2 diabetes. I’ve never heard of that at all.’

He also ruled out it being linked to Hanks previously having COVID.

Robert H. Eckel, board member of the American Diabetes Association and a past president of the American Heart Association, told DailyMail.com that, in general, people with diabetes could shake if their blood sugar got too low.

‘People living with type 2 diabetes and being treated with insulin or sulfonylurea may experience shaky hands if their blood glucose gets too low, which is a condition called hypoglycemia,’ he said.

‘There are a lot of potential reasons someone may experience shaky hands.

‘Whether you have diabetes or not, if you experience changes in your hands, feet or legs, you should work closely with your health care provider to determine the cause and appropriate treatment, if necessary,’ he said.

Lisa Kudrow recently critiqued Tom’s new film Here, condemning the usage of digital de-aging.

The 61-year-old actress said the new fantasy drama film was an ‘endorsement for AI.’

In the movie, which was released on October 25, Hanks reunited with Forrest Gump costar Robin Wright in a multi-generational story, which depicted the cast as their characters over several eras.

It followed last year’s SAG-AFTRA and WGA strikes calling for regulation of the modern technology.

The Friends star appeared on a recent episode of Dax Shepard’s Armchair Expert podcast and blasted Hank and director Robert Zemeckis’ film.

‘They shot it, and they could actually shoot the scene and then look at the playback of them as younger, and it’s ready for them to see,’ she explained on the podcast.

‘And all I got from that was, this is an endorsement for AI and oh, my God. It’s not like, “Oh, it’s going to ruin everything,” but what will be left? Forget actors, what about up-and-coming actors? They’ll just be licensing and recycling,’ she argued.

Kudrow continued: ‘Set that completely aside, what work will there be for human beings? Then what?

‘There’ll be some kind of living stipend for people, you won’t have to work? How can it possibly be enough?’
