The Steve Jobs biopic called "jOBS" starring Ashton Kutcher is premiering next week at the Sundance Film Festival.
Gad told Bryan Alexander of USA Today that he studied "literally hundreds" of hours worth of Wozniak footage.
"This was definitely outside my wheelhouse," Gad said. "I felt like I was going to college."
Regarding Kutcher's role as Jobs, Gad said "there is an eerie resemblance."
