"Igor" was produced over the course of two years beginning in November 2006. Due to "Igor"'s inspiration originating from a European nation and being most famous in the continent of Europe, Howard wanted to have a European studio responsible for the animation's aesthetic. He chose Sparx Animation Studios, where its French office did the designs and used $4 million worth of tech for making the film. It was Sparx's first theatrical film, as their previous work were direct-to-video products and television productions such as "Rolie Polie Olie" (1998–2004) and "Mickey's Twice Upon a Christmas" (2004). A chunk of the 65 Sparx artists and Leondis previously worked at Walt Disney Animation France, and appreciated the amount of freedom they had when working on "Igor". Leondis explained, "At Disney everything had to be done in the house style, but here they really wanted to push boundaries. I came in and said, 'We're going to do something sumptuous, something sophisticated, something crazy. We're going to mix freaks, skulls and the generally creepy with the architecture of the Liberace museum.'" "Igor" was the last production of Sparx before it shut down its French offices a few months after the film's release.
