Star Trek: 10 Things You Didn’t Know About The Guardian Of Forever
5. You've Heard Its Voice Before
In The City On The Edge Of Forever, the Guardian was voiced by Bart La Rue. This was one of many roles for the vocal actor in Star Trek, though he would actually only appear on-screen in two episodes - Bread And Circuses and Patterns Of Force.
He was known for his deep baritone voice, and as such would often be cast in other vocal roles. He voiced one of the Providers in The Gamesters of Triskelion, as well as the Excalbian in The Savage Curtain.
He originally left college to work as a clown, but returned and achieved a BA in Theatre Studies. He spent several years working as a character actor, and produced several independent films before his premature death from a heart attack at age 57. His voice would, however, return to Star Trek, via archived recordings, in the Discovery episodes Terra Firma, pts 1 and 2.
