Cars 3

In June 2017, Entertainment Weekly reported that during the voice-actor recording process for Cars (2006), director John Lasseter spent a lot of time in the recording booth with Paul Newman, who often regaled him with stories about his life and his many years as a race car driver. Lasseter said, "In a way, he mentored me in racing, because car racing was his true life's passion, and I made sure that whenever he came into the recording booth, we were recording everything. In-between takes, he would tell me stories about great races, and you could hear the passion in his voice." Those recordings made it possible for Doc Hudson to reappear in this movie, released over eight years after Newman's death. Lasseter explained, "as we started Cars 3, we went back to every recording we did on Cars 1 and catalogued and listened to it all, and ended up with a lot of material that we could use; lines that were cut from the original film and never used, as well as some of those pieces from in-between takes."

During the first race montage, Lightning is shown coming into the pits. Once in his pit box Guido can be seen and heard undoing multiple lug nuts on his left front, but when the new tire goes on, only 1 lug nut is tightened before Guido moves to the back tire.

"This film is dedicated to our families. Your love and support made this film possible."

The 3D version bears a different version of the Pixar logo than the 2D version, with the Pixar lamp hopping toward the camera instead of coming in from the right side.
