Pixar: 20 Years of Animation and Counting is a documentary film hosted by John Ratzenberger. The program aired in 2006 on The Wonderful World of Disney ABC series, and was originally titled "Pixar's 20th Anniversary Special." The 3-hour documentary showed how Pixar went from a humble little CG studio (producing shorts and TV commercials) to the animation powerhouse studio we know today.
Written, directed and produced by Leslie Iwerks (granddaughter of pioneer Ub Iwerks), it also featured appearances by filmmaker George Lucas, Steve Jobs (of Apple fame who purchased the studio from Lucas and turned it into Pixar), Pixar's chief creative officer John Lasseter and Roy Disney. Also appearing was Tom Hanks (the voice of Woody), Tim Allen (the voice of Buzz Lightyear), and Billy Crystal (the voice of Mike Wazowski).
