His hugely successful sitcom The Big Bang Theory came to an end in 2019 after 12 seasons.
And now Jim Parsons is talking about how he came to the decision to pull the plug on the CBS show that made him famous, won him four Emmys and earned him the Forbes title of world's highest-paid TV actor of 2018.
Speaking to former Doctor Who star David Tennant for an episode of the Scottish actor's podcast, Parsons explained that the summer of 2018 had been 'really intense' and 'I had this moment of clarity that ... 'I gotta make a move.''
'I was exhausted': Jim Parsons has revealed that a 'really intense' summer in 2018 during which his dog died led him to his decision to walk away from his hit CBS sitcom The Big bang Theory
Parsons started playing Sheldon Cooper in 2007 alongside a cast that included Kaley Cuoco, Johnny Galecki, Mayim Bialik, Simon Helberg, Kunal Nayyar and Melissa Rauch.
But after filming season 11, he spent his hiatus from the sitcom starring on Broadway in The Boys In The Band.
During that time, his beloved 14-year-old dog died and he started to feel overwhelmed.
'I was exhausted,' he told Tennant, as reported by the UK's Radio Times.
'I felt like I was at the edge of a cliff. I was teetering and I saw something really dark below between the death of the dog.'
