Spaceballs (1987)

On the peaceful planet Druidia, King Roland attempts to marry his daughter Princess Vespa to Prince Valium, but Vespa and her loyal droid Dot Matrix escape during her wedding. After wasting the fresh air on the distant planet Spaceball, corrupt President Skroob orders the arch-villain henchman Dark Helmet to kidnap Princess Vespa to force King Roland to provide them with the code to Druidia’s atmosphere. Under those circumstances, the seasoned mercenary Lone Starr and his devoted half-human, half-canine sidekick Barf try to save the princess. In the meantime, the ruthless loan shark Pizza the Hutt is after them. But only he who can harness The Schwartz, a mystical cosmic force, will save the day.
