Star Trek actor Zachary Quinto has paid tribute to his co-star Anton Yelchin, who died last month at the age of 27 in a freak car accident.
Zachary told of the devastation of the whole cast during an appearance on The Late Show With Stephen Colbert.
Calling Anton a "beautiful, beautiful guy," he said: "I don't even know how to talk about it.
"We already knew this was going to be a bittersweet experience as a result of the loss of Leonard [Nimoy, who died in February 2015].
"But this has been absolutely devastating for all of us. I think our goal just has to be to celebrate his incredible life and honor him. It was a terrible loss, not only to us but to audiences and the industry."
The young actor died on June 19 after his car rolled down his sloped driveway while set in neutral, pinning him between his security gate and a brick mailbox.
Zachary, who first found fame in Heroes and plays Spock in the Star Trek movies, said the loss was even harder because and the rest of the cast were all so tight-knit.
He said: "We are truly and inextricably entwined and I think we always will be.
"Our goal has to be to celebrate his incredible life and honour him as much as we can.
