"Toy Story"s script was strongly influenced by the ideas of screenwriter Robert McKee. The script went through many changes before the final version. John Lasseter decided Tinny was "too antiquated", and the character was changed to a military action figure, and then given a space theme. Tinny's name changed to Lunar Larry, then Tempus from Morph, and eventually Buzz Lightyear (after astronaut Buzz Aldrin).
