There are visual references to Jurassic Park and Raiders of the Lost Ark, sound effects lifted from Star Wars, and an extended parody of The Empire Strikes Back which acknowledges its own silliness and is funnier than Spaceballs and more good-humored than what Lucas is doing these days.
And yes, you could spend multiple viewings of Toy Story 2 looking for the inside jokes: Tour Guide Barbie (Jodi Benson) admonishing passengers bilingually a la Disneyland to "remain seated please" in a toy car; high-speed channel surfing including Pixar shorts like Tin Toy and Luxo Jr.; a toy repair expert (Jonathan Harris) whose face recycles the star of the Oscar-winning short Geri's Game; genial pokes at Tron, Jurassic Park and The Empire Strikes Back.
The script, which Lasseter supervised with half a dozen writers contributing, is sharp and quick, jam-packed with perceptive plaything humor ("I'm packing your angry eyes, just in case," says Mrs. Potato Head) and hilarious homages to old westerns, "Star Wars," early Pixar shorts and an especially side-splitting "Jurassic Park" spoof.
Parodies are kept to a minimum, although there's a funny takeoff on a key element of the Star Wars series in addition to a quick, throw-away moment lifted from Jurassic Park .
As a cadre of Andy’s toys — Hamm the piggy bank (the voice of John Ratzenberger), Slinky Dog (the voice of Jim Varney), Mr. Potato Head (the voice of Don Rickles), and Rex the dinosaur (the voice of Wallace Shawn: My Favorite Martian), all led by Buzz Lightyear (the voice of Tim Allen) — attempts Woody’s rescue, the audience is treated to numerous and hilarious salutes to all manner of GenX obsessions: Star Wars, video games, Jurassic Park.
The opening sequence is a funny and clever parody of both the Star Wars and Star Trek series, and the filmmakers work in great visual gags that play off scenes in Jurassic Park (1993) and Die Hard (1988).
