In honor of Star Wars Day ("May the Fourth be with you!"), here are miscellaneous mishaps and oddities from all six films.

Episodes IV, V, VI

My favorite part: around 3:15, an AT-AT catches fire, revealing its true scale.

Episode I

R2-D2 has serious stability problems. Bonus: His lines, Yoda messes up.

Episode II

Anakin face-planting, falling down during a lightsaber battle, and spitting out overly hot soup.

Episode III

There was "Nooooooooooo!" official blooper reel for Episode III, so some YouTube person cut together behind-the-scenes footage of wacky stuff. My favorite? C-3PO falling down unintentionally, and Samuel L. Jackson falling down intentionally.
