Thirty years later, Tom Hanks reveals how an original version of Toy Story was "completely thrown out." Hanks voiced Woody in the first Toy Story movie released in 1995, while Tim Allen voiced Buzz Lightyear, and they have continued to voice the beloved characters in the decades since then.
Stephen Colbert brought up the 30-year anniversary when Hanks came onto The Late Show with Stephen Colbert . Hanks clarified that it had actually been more than 30 years, though, because he and Allen recorded lines for an earlier version of the movie that was scrapped. Check out his explanation below:
