Kenneth Mitchell, Known for ‘Star Trek’ and ‘Captain Marvel’ Roles, Dies at 49

Kenneth Mitchell, a Canadian actor known for his roles on the series “Star Trek: Discovery” and the film “Captain Marvel,” died on Saturday. He was 49.

He had lived with the neurological disorder amyotrophic lateral sclerosis, or A.L.S., which causes paralysis and death, for more than five years, according to a statement from Mr. Mitchell’s family posted to his social media.

Mr. Mitchell played the Klingons Kol, Kol-Sha, and Tenavik, as well as Aurellio, on “Star Trek: Discovery,” and voiced several other characters in an episode of “Star Trek: Lower Decks.”

In “Captain Marvel,” he played the father of the superhero, Carol Danvers. He was also known for portraying Eric Green on the series “Jericho,” Joshua Dodd in the series “Nancy Drew,” a hockey player in the film “Miracle,” and appeared in several other film and television series.

Mr. Mitchell lived with his wife, the actress Susan May Pratt, and their children in Los Angeles. He was born on Nov. 25, 1974, in Toronto to Diane and David Mitchell.

In 2018, Mr. Mitchell was diagnosed with A.L.S., according to a statement posted to his social media in August. He revealed his diagnosis in an interview with People Magazine in 2020, saying that from the moment he found out, it was “like I was watching that scene where someone is being told that they have a terminal illness.” He added, “It was just a complete disbelief, a shock.”

Mr. Mitchell said he focused on spending more time with his family and rejected a lead role in a television series that required moving back to Canada. The makers of the series “Nancy Drew” also accommodated for his illness, he told People, using a stunt double when needed. Other roles were created for him that allowed him to be seated, he added.

“This disease is absolutely horrific,” Mr. Mitchell said in the post last year, which accompanied a photo of him watching the sunset from a wheelchair on the beach. “Yet despite all the suffering, there is so much to be grateful for,” he added.

Mr. Mitchell is survived by his wife, their children Lilah and Kallum, his parentsand other family members, according to the family statement.
