If you’re a fan of Pixar movies such as Toy Story and The Incredibles, you may have noticed a familiar voice. John Ratzenberger has been in every single Pixar movie to date, starting with Toy Story in 1995 and continuing all the way through the next Finding Nemo movie, currently scheduled for a 2016 release.

Ratzenberger isn’t sure why he has become Pixar’s lucky charm, but Pixar knows. Writer/producer Andrew Stanton said they had so much fun hanging out with him at the first Toy Story press junkets, they decided to work with him as much as possible in the future. And director Pete Docter just thinks Ratzenberger’s vocal work is recognizable. “He's someone so clear, I know that guy after only two lines of dialogue. Having him in every film is like our Hitchcock cameo."

In case you’ve missed some of those appearances, here they are.

"What you wanna do is follow the EAC, that's the East Australian Current. Big current, can't miss it, it's in that direction. And then you gotta follow that for about, I don't know, what do you guys think? About three leagues? And that little baby's gonna put you right past Sydney."
