Actor James Darren, known for his work on films including Gidget and TV shows such as T.J. Hooker and Star Trek: Deep Space Nine, has died at the age of 88.
TMZ report that the veteran performer passed away in his sleep at Cedars-Sinai Hospital in Los Angeles on Monday.

Darren’s cause of death remains unknown a the time of writing, but the actor’s son, Jim Moret, reportedly told TMZ that his father was having heart issues and was a patient at Cedars-Sinai’ cardiac unit.
It’s believed that Darren had initially gone to hospital for an aortic valve replacement, only to be judged too weak to safely undergo the procedure.

He was subsequently sent home, but returned to hospital a short time later.

“I always thought he would pull through,” his son Jim said, “because he was so cool. He was always cool.”
