Speaking about his time on the show, which originally ran from 1966 until 1969, Shatner told The Daily Telegraph: “Nobody knew about reruns.
“The concept of syndication only came in after Star Trek was cancelled when someone from the unions said, ‘Wait a minute, you’re replaying all those films, those shows.’
“There was a big strike. But in the end, the unions secured residual fees shortly after Star Trek finished, so I didn’t benefit.”
However, Shatner insisted the programme did pay him well.
He said: “It paid very well for me in my experience up to that time.
“But by the standards of Hollywood, not very well – and with a dissolving marriage, with three children, I was broke at that point.”
