While Spock is travelling through Vger, encountering the holographic images, he passes under two curious ones - Darth Vader and Miss Piggy.

Mark Lenard, who played Spock's father, Sarek, in the original series, is the only person to play a Romulan ("Balance of Terror"), a Vulcan (Sarek), and a Klingon. He played the Klingon Captain in the final Klingon ship to be destroyed by V'Ger.

A constant question during the run of all the Trek series is why Klingons look so much different from Star Trek: The Motion Picture on than they did in the original series. The real reason is the movies and later TV series had a better makeup budget. However, the Star Trek: Enterprise episodes "Affliction" and "Divergence" provide a canon answer. Klingons acquired genetically engineered human embryos left over from Earth's Eugenic Wars and used them to augment their soldiers. It worked but created a virus that threatened to annihilate the Klingon race. Dr. Phlox and a Klingon doctor found a cure, but it resulted in all Klingons becoming far more human in appearance. Sometime between these episodes and the first Trek movie a cure was found, returning the Klingons to their present day "ridged-head" appearance. Submitted by Grumpy Scot

This was the first motion picture to be promoted by a McDonald's Happy Meal. Submitted by wizard_of_gore

The film was originally the pilot for a TV series, "Star Trek II." The series was aborted shortly before production began, and was re-written as "Star Trek: The Motion Picture."

It must be nice to be the captain. Kirk's chair now has arms that fold down across his lap to hold him securely in place. However, they decided that just about everyone working along the sides of the bridge doesn't even deserve a chair. Submitted by Garlonuss
