Jason’s TV appearance followed public concern about his health.
The star was spotted looking frail last year after attending a performance at the Oxford Playhouse last summer.
The actor also spoke about how he was finding life difficult during the pandemic.

“I mean they are really difficult and trying for everyone, moi included, but stick with it and try to do what the government says.”
