Puss In Boots:12 Facts About The Shrek Spin-Off For Feline Fans Everywhere

It's funny how irony works. Released in 2001, "Shrek" wasn't so much an adaptation of William Steig's children's book so much as an excuse to satirize Disney cartoons (including surprisingly adult jokes for a kid's movie). "Shrek" was so successful it became a four-film franchise, and with the spin-off movie "Puss in Boots" it became a bonified cinematic universe. A fan-favorite supporting character, Puss in Boots proved able to carry an entire movie of his own.

Now that the long-awaited follow-up "Puss in Boots: The Last Wish" has enjoyed a surprisingly extended life at the box office on the strength of its sincere meditation on mortality, it's worth revisiting the story of the original "Puss in Boots." A decade after the feline was introduced in "Shrek 2," Puss had become a legend of his own. "Puss in Boots," forging a new identity separate from the snark and arch comedy that defined the 2000s, was free to dabble in more Pixar-like emotional depth and character work. Here are 12 facts about "Puss in Boots" fans of fabled felines everywhere should find fundamental.

Antonio Banderas would gain acclaim in his early career in Spain, most notably in the films of auteur Pedro Almodóvar, but he arrived in Hollywood in the early 90s speaking only minimal English. As he told the New York Times, "I couldn't speak the language. At all. I did my first movies learning the lines phonetically, and I had an interpreter to talk to the director. Suddenly, years after, to be called for the use of my voice only, it was interesting. And pretty weird."

By the time "Shrek 2" came out in 2004, not only was Banderas's English impeccable, but his still-noticeable accent had become the opposite of a liability. His iconic performances in movies like "Interview with the Vampire," "Desperado" and "The Legend of Zorro" are what made his voice instantly recognizable, to the point that he would be cast as Puss in Boots specifically to give the character a built-in personality. Nowadays he's just as associated with voice roles (chiefly Puss in Boots and the Nasonex bee) as with his famous live action parts.

"Puss in Boots" does have some elements of the "Shrek" franchise. Notably, it plays with fairy-tale conventions by having grotesque adult versions of Jack (Billy Bob Thornton) and Jill (Amy Sedaris) as the villains. Though it partakes in the practice of toying with the foundations of fairy tales, "Puss in Boots" opted for a more heartfelt and straightforward tone than the PG edge of the reference-happy "Shrek". To give its swashbuckling hero a proper origin story, the movie had to take the legend of Puss in Boots at least half as seriously as the legend himself.

In an interview with Fantasy Magazine, writer-director Chris Miller explained the desire to distinguish the spin-off from its source. "Now we knew that we were going to have the fairy tale world as a backdrop in 'Puss in Boots,' we wanted to make sure we didn't end up just parodying them. We wanted to take the original stories and put a new spin on them ... since we weren't satirizing anything, we wanted to make sure the film was all about character and interesting relationships, and let those drive the comedy."

Although it wasn't as tongue-in-cheek as "Shrek," "Puss in Boots" did take a measure of pride in sticking to the same tradition of subverting traditional fairy tale expectations. Childhood legends Jack and Jill are brutish, adult outlaws. The benevolent figure of Mother Goose becomes a two-story-tall monster that nearly destroys the town. But the biggest challenge in coming up with an original take on a fairy tale legend was the largest character of them all (literally): the giant that lives at the top of the beanstalk. And "Puss in Boots" wanted to ensure that its approach was different from other films.

Director Chris Miller told Animated Views "we wanted to just make a straight-up giant, like a real fairy tale legendary giant. And no matter how hard we tried to twist the character there was something about it that felt so expected. Once you did see him it wasn't surprising, no matter what we did." So instead, in the ultimate subversion of expectations, the giant was killed off-screen, resulting in just another red herring obscuring Humpty as the true villain of the plot. 

Two members of the "Puss in Boots" voice cast were comedians brand new to voice-over work: Zack Galifianakis as Humpty and Amy Sedaris as Jill. To take advantage of their backgrounds in stand-up comedy and improv respectively, director Chris Miller gave them free rein to improvise lines in the vocal booth, which yielded particularly impressive results, especially in Sedaris's case. It apparently got to the point where the writers relied on Sedaris's off-the-cuff abilities instead of finding lines they were happy with in advance. It turned out to be a savvy move, as Jill provides some very valuable comic relief.

Miller revealed to Animated Views that "with Amy we'd write lines that we knew were just in the ballpark that we needed and honestly she would give us fifty different versions of something, and that's no exaggeration." With so many options to choose from, the vast majority of the part of Jill was made up by Sedaris on the spot. Per Miller, "probably ninety percent of her dialogue came out of her brain." Galifianakis told Collider that for his part he improvised liberally but "I don't know how many they used in the movie 'cause it's a kids' movie and I probably just went off the rails a little bit."

Arguably going back to the casting of Robin Williams in Disney's 1992 film "Aladdin," the practice of casting recognizable celebrities in animation has become more and more widespread. "Puss in Boots" and the "Shrek" franchise at large are certainly no exception. In practice, this often means that famous actors do voice work but aren't even asked to "do a voice" in any way — they often speak like themselves in order for people to recognize who it is. In an interview with Fandom Entertainment, Billy Bob Thornton says his assignment as Jack was simple: "I essentially didn't have to do much... I just kind of show up and start talking."

He did point out, however, that he modified his voice slightly to reflect the main difference between himself and his character: "I weigh 145 pounds, and this guy weighs 300 pounds or something." So to embody Jack he had to try and affect a more robust, booming version of his speaking voice to match the strength and power of the villainous Jack. Fortunately, he didn't have to fall down any hills for research.

In a wide-ranging interview with Animated Views, "Puss in Boots" composer Henry Jackman explained that the movie offered a unique opportunity for a fantasy film. Instead of the traditional symphonic score with a full orchestra, the setting and character-specific elements of "Puss in Boots" meant it could be distinguished with many different tones, incorporating the flavor of its Spanish inspirations. The result was a liberal use of solo guitar: Jackman said that "the use of solo instruments can really bring the melodies forward and it makes it closer and more intimate and more individual...on top of that, we had the added benefit of having Rodrigo and Gabriela play the guitar parts of the score which I wrote."

The Mexican-born acoustic guitar duo, who perform as "Rodrigo y Gabriela," actually rose to fame in Ireland after emigrating from Mexico in 1999. But they're pioneers in the genre of "nuevo flamenco," or flamenco fusion: music that blends a classical Spanish style with modern rock techniques. This made them the perfect artists to collaborate with on "Puss in Boots," as it also sought to combine Spanish heritage with a modern sensibility.
