Sir Ian is recovering after his fall on stage earlier this year and also revealed that he is looking to “take the rest of the year off” from acting.
The actor lost his footing during a play’s fight scene in June at the Noel Coward Theatre and has since been suffering from wrist and neck injuries.
Sir Ian was two months into a season of Player Kings as John Falstaff when he fell from the stage into the first row of the audience
He said he has been “left feeling weak physically” from the fall during the production adapted by Robert Icke from Shakespeare’s Henry IV parts one and two, and that he is doing exercises to treat the issue.
“Of course, it’s emotional,” he said. “We all trip all our lives, it’s just when you get to my age you can’t always get up again.”
The Burnley-born actor suggested he is concerned that the fall could have been the result of him getting old.
“I’m just trying to convince myself it was an accident,” he added. “I’m usually working or preparing to work, I’ve been doing a little bit of that, wondering what might be the best plan. I’m going to take the rest of the year off. Not because I need to, just because I want to.”
Protected by fat suit
Sir Ian previously said a fat suit worn for the production is believed to have saved his “ribs and other joints”.
The actor also spoke about the US presidential election and said he hoped Vice President Kamala Harris would win the battle against former president Donald Trump.
He said: “Though we’re not Americans, we have a right to be interested and concerned. It’s not an internal affair. The president in the United States can be a force for good and not good.”
Asked if he supported Ms Harris, he said: “There’s no choice, is there? Oh dear, Trump is so blatantly what he is, which is slightly reassuring.
“Other wicked politicians have disguised themselves, it’s all on display with Trump: his prejudices, his ignorance, his stupidity, his incompetence, his lack of experience in matters that matter.
“One impressive message to come out of Chicago has been saying we must listen to each other. Nothing wrong with having a good argument but let’s hear what the disagreements are. You discover that your differences may be huge but, actually, there are a lot of similarities that bring people together.”
