↳ ’Actor Allusion’ with Jack Donaghy:
A joke or reference which is specific to one of the actors in a show. It can be a little blink-and-you’ll-miss-it moment, or it can be bigger and more blatant. It sets up a character or plot to reference a previous plot or role for the actor.
(Alec appeared in a television campaign for Capital One, and once narrated the children’s TV series, “Thomas and Friends”.)
