Spaceballs tells the story of Han Solo-aping hero Lone Starr (Bill Pullman) and his half-man, half-dog sidekick Barf (John Candy, perfectly meeting the level at which the humor is aimed—namely, someone who would find a sidekick named “Barf” to be inherently funny). Lone Starr is hired by King Roland (Dick Van Patten) to rescue his daughter, Princess Vespa (Daphne Zuniga), and her C-3PO knockoff of an aide, Dot Matrix (voiced by Joan Rivers). See, they’ve been captured by Spaceballs—a race of beings that are in dire need of fresh oxygen, after using up their planet’s supply. Kidnapping the princess was part of a scheme to steal the oxygen from Vespa’s home planet of Druidia. The plot follows our heroes as they rescue the princess; Lone Starr and Vespa engage in some “I hate you/I love you”-style banter, fall in love, and win the day; and the bad guys are thrown halfway across the galaxy. But the real winners are the teenage boy audience.
