Alternatively, there could be the possibility for a fourth Cars movie that doesn’t focus on Lightning, in the same way that Cars 2 was a movie much more about Lightning’s buddy Mater.
So while Brian Fee was not willing to commit to another Cars film, he’s certainly leaving things open to the possibility.
During a recent Cars 3 press day I was able to attend, the new film was described as the “3rd act” of Lightning McQueen’s career, which would seem to indicate the end of a particular road, but, as Fee says, maybe McQueen has a fourth act left in him, perhaps even more.
