"Steve Jobs" drew high praise from some reviewers and critics on its debut at the Telluride Film Festival on September 5, reported Aceshowbiz.
Michael Fassbender stars in the titular role.
Wozniak was among the viewers, praising the movie and 38-year-old Fassbender, whom he considered successful in portraying the Apple former chairman.
"I saw a rough cut and I felt like I was actually watching Steve Jobs and the others, not actors playing them, I give full credit to Danny Boyle and (screenwriter) Aaron Sorkin for getting it so right," Wozniak said.
