According to Pauley, the incredibly realistic storm scene wouldn’t have been possible in earlier films. Interestingly, in the first Toy Story movie, filmmakers also wanted to create a rainstorm in the scene where Woody and Buzz are trapped in Sid’s room, however, they were limited by both the technology and experience on the team. So they compromised and instead of showing pouring rain outside, they created shots in which the rain dripped on the window from inside the bedroom.

“It was every bit as emotional and important to the storytelling, but we just used a creative way to not have to do rain,”  Pauley recalled.
