American actor (1928–2019) who played the Romulan Subcommander Tal in the original series episode The Enterprise Incident and, more than three decades later, a Vulcan priest in Star Trek: Enterprise.
Jack Donner was an American character actor whose Star Trek work spans two eras of the franchise. In 1968 he played Subcommander Tal, the suspicious second-in-command to the Romulan Commander, in The Enterprise Incident.
He returned in the fourth season of Star Trek: Enterprise as a Vulcan priest. In Home he officiates at the wedding of T'Pol and Koss, and he appears again in Kir'Shara, when the couple's marriage is dissolved.
Donner is one of a small number of performers to have acted in both the original 1960s series and Enterprise, and he played members of the two related species, Romulan and Vulcan, in doing so.
