In casting the leading voices for "Toy Story," the filmmakers always wanted Tom Hanks for Woody. John Lasseter was a fan of Tim Allen in "Home Improvement," but nobody else had ever heard of him. Even so, they cast Allen in the role and shortly afterward, Hanks' and Allen's fame began to skyrocket due to "Forrest Gump," "Apollo 13" and "Home Improvement."
The folks at Pixar originally approached Billy Crystal, the voice of Mike Wazowski in "Monsters, Inc.," to do the voice of Buzz Lightyear, but he turned them down.

Animator Doug Sweetland spent so much time animating Buzz's overreaction to Woody's accidentally opening Buzz's helmet that he didn't have time to animate Woody's reaction to Buzz's dramatics. He inserted a little shot of Woody turning his head to fill the space, and the filmmakers said they just fell down laughing. They added some blinking on Woody's part and declared the scene done.

In the scene where Woody tries to make Buzz fall behind the desk in Andy's room, the filmmakers used "Indian Jones and the Raiders of the Lost Ark" as their inspiration, to the point of incorporating the sounds of the iconic rolling boulder and shooting arrows from that movie as the globe rolls toward Buzz and pushpins shower down.

In the rescue scene at Sid's house, Woody utters the line, "Wind the frog." Joss Whedon — known for shows like "Firefly" and "Buffy" and the movie "The Avengers" — wrote that line, and the filmmakers liked it so much that they created the wind-up toy frog specifically so they could use it.
