“Currently shooting some of my final episodes as ‘Captain Cold/Leonard Snart’ on the CW’s Legends of Tomorrow and The Flash,” Miller wrote on Instagram. “Grateful — now and in advance — to a pair of talented casts and hardworking crews … Thank you. … I”ve had a tremendous time playing this character. … It’s been an opportunity, an education and a f—ing blast.”
The CW did not immediately respond to Variety‘s request for comment.
Miller first began playing Captain Cold in 2014 on “The Flash,” appearing in multiple episodes before becoming a regular on “Legends of Tomorrow,” the latter of which also starring fellow “Prison Break” alum Dominic Purcell. Miller is the latest member of the “Legends” cast to announce his departure, with Victor Garber also recently announcing he will leave the show to perform on Broadway.
