Soul made its Disney+ debut on Christmas Day of 2020, and on first viewing, it seemed as though seasoned Pixar voice actor John Ratzenberger didn't have a part in the film – but he does. Many voices in Soul are easily recognizable, but it's somewhat difficult to make out Ratzenberger's signature gruffness anywhere. After several fans commented on not being able to discern his voice, director Pete Docter confirmed in an interview with CinemaBlend that Ratzenberger does indeed make a very brief appearance in Soul, but declined to give specific details.
