Joe E. Tata (born September 13, 1936) may have played the voice of Zalto's Dummy in Rocket to Earth. He is listed on IMDb; however in an interview at LIS Memories, it states that Bob May played the role. Also, he played the voice of the Dranconian computer eye in The Cave of the Wizards (uncredited), which were both on the Lost in Space series, as well as playing the small role of Napoleon Bonaparte in The Time Tunnel episode of "Reign of Terror". Tata's father was a star in Vaudeville.[1]
