Chris recently announced he was taking a break from acting to spend more time with his family after discovering he was at risk of Alzheimer's disease.

The Marvel Universe star told Vanity Fair he'd decided to take 'time off' after filming a confronting episode about death for his new Disney+ docuseries Limitless.

'It really triggered something in me to want to take some time off. And since we finished the show, I have been completing the things I was already contracted to do,' he said.
