Distinguishes between films made for a theatrical experience and movies made for television by assessing the performance of the actors in a non-qualitative but descriptive manner. Originates from the distinctive acting style of the inimitable William Shatner. The Shatner Effect occurs when it is obvious a work of entertainment is made for television based upon the delivery of the actors.
You: "How can you tell this movie was made for TV?"
Me: "Note that actor's dramatic gesticulations. Observe the overly tremulous voice. Check out the zipper on that alien costume. The Shatner Effect, totally."
