Pocket Flix Star Trek Starter Set

Pocket Flix was a battery-operated handheld motorized movie viewer produced by Ideal Toys in 1978. The unit allowed you to view interchangable circular movie "cassettes" and see clips from your favorite TV shows, cartoons and movies. The unit was sold with various "starter" cassettes, including a Star Trek cassette with footage from the Star Trek: The Original Series episode "By Any Other Name". The cartridge was also available separately. No footage of the Spock character was included as Leonard Nimoy was involved in a lawsuit with Paramount over the use of his likeness for licensed Star Trek merchandise at the time the toy was released.(citation needededit)
