Jack Donner is an American actor whose career in theater, television and film has extended over six decades.
A native of Los Angeles, Donner has worked steadily in television and film since the 1950s including early work on The Guiding Light and As the World Turns. Honing his craft, he performed in seven successive seasons of New York regional and stock theater.
In the 1960s and 1970s he started to receive guest star and co-starring roles in shows such as The Man from U.N.C.L.E., Mission Impossible, Mannix, Kojak and The Streets of San Francisco. However, Donner is probably best known for his role of Romulan Subcommander Tal in the original Star Trek episode \"The Enterprise Incident\". He would later return as a Vulcan priest in the episodes \"Kir'Shara\" and \"Home\" of Star Trek: Enterprise. Along with Joseph Ruskin and Clint Howard, he is one of only three actors to appear in both the original Star Trek series and Star Trek: Enterprise. In 1998 he appeared in the uncredited role of Commander Kinwon in Power Rangers in Space. He has had a recurring role on General Hospital as Nikolas and Spencer Cassadine's butler Alfred.
