ANAHEIM, Calif. -- Can you believe it's been 30 years since the first "Toy Story" came out? A panel on Friday at D23 in Anaheim, Calif. was held to recognize this beloved film and share how it all came together.

D23 LIVE UPDATES : Latest from Disney's ultimate fan event in Anaheim The panel included Katherine Sarafian, Pete Docter, Andrew Stanton, Bonnie Arnold, Bob Pauley and Jonas Rivera. The Pixar of the '90s, at the time the film was made, was described by Pauley as a "scrappy startup." The technology they used was cutting edge and Stanton described it as "building the plane as you're flying it.

" Arnold continued that sentiment, estimating that while groundbreaking films "Jurassic Park" and "Forrest Gump" had around 200 special effect shots each, "Toy Story" had 16,000. Docter shared a limitation of the technology, noting that during the scene in which Woody sneaks into the restaurant under a cup, if you look closely, you'll notice all of the diners in the restaurant are frozen when they should be moving. During the panel, a picture of Woody's pull string phrases was shown.

Stanton revealed that Tom Hanks had recorded himself saying all of them, noting that the last handwritten three are ones the actor came up with on his own. "There's a snake in my boots" was a favorite of the crew's and has become a well-quoted line. Another well-known and simple line, "I'm the one that should be strapped to that rocket," which showed Woody's insecurities, was borne out of frustration.
