Interesting tidbit about Justin Theroux regarding The Leftovers
When screenwriter and producer Damon Lindelof first imagined the character of Kevin in The Leftovers, he pictured a deeply angry man. This changed, however, when the showrunners were impressed with Justin Theroux's portrayal of the character as scared and vulnerable rather than angry.
“I really do believe that a lot of the best ideas that we’ve had for the show were inspired by choices that the actors themselves were making,” Lindelof told Backstage in 2017. He continued:
Our original plan for Kevin Garvey was that he was a cop who had all this anger inside him, and because he was repressing that anger, it was creating all these issues. But then Justin started playing him in a much more vulnerable way, and we started writing to that idea.
