It comes after the busy actor announced that he would take some time away from the spotlight to spend time with his family.

The Rush actor told Vanity Fair last November he’s having some ‘time off’ after filming a confronting episode about death on his new Disney+ docu-series Limitless.

Playing on Chris’ stardom through superhero movies, Limitless follows him as he pushes up against the boundaries of what his body can do.

He is seen on the Disney+ program pursuing various physical goals, such as what Variety reports was 40lbs of weight gain for a Thor film.
