American actor (born 1959), famous for Seinfeld, who played the manipulative Kurros in the Voyager episode Think Tank and later voiced the Tellarite Doctor Noum in Prodigy.
Jason Alexander is an American actor and director best known as George Costanza in Seinfeld. A long-standing Star Trek fan, he took a role far removed from his comic image.
In the fifth-season Voyager episode Think Tank he plays Kurros, the soft-spoken spokesman of a group of alien intellects who solve problems for a price and who want Seven of Nine as payment for helping Voyager escape Hazari bounty hunters.
He returned to the franchise in the animated series Prodigy as the voice of Doctor Noum, the blunt Tellarite physician serving under Admiral Janeway aboard the USS Dauntless.
