Currently a mere $27,000, this Heritage Auctions listing for Spaceballs (MGM, 1987), Group of (5) Spaceballs Action Figures are the real deal - that is to say, movie props, as there are no licensed action figures for the movie.

There's clearly demand for these, and if you really want them, this auction listing ends in two days.

In it, you get Barf, Lone Starr, Princess Vespa, Dot Matrix, and of course, Dark Helmet. None of these were ever mass-produced, and George Lucas himself supposedly told Mel Brooks he couldn't make Spaceballs action figures. I have been involved in many a conversation about the property over the past couple of decades and it never goes anywhere.
