The BUCK ROGERS IN THE 25TH CENTURY TV series, unsurprisingly, spawned a line of STAR WARS-scaled action figures and here is a advert for them from a US comic cover-dated June 1980.
All the figures came from the show's movie/ pilot... including Draco who, in Larson's final theatrical and TV cut, barely featured but was obviously intended to play a far larger part judging by the merchandising.
Unfortunately, the various DVD releases (no BR unfortunately) of the movie and TV show comes sans deleted scenes (unlike the copiously endowed BATTLESTAR GALACTICA release… coming soon to UK BR. Hurrah!) so we've not had a chance to find out.
The LORD OF THE RINGS figures, unlike Twiki, ring no bells...
