Not a ripoff but a fucking coincidence. The movie that premiered first started recording second.

It's way underrated, but watch Dick Tracey with Warren Beatty and Madonna. She gives the best performance of her career and the movie makers used a lot of great tricks to make it look like an old time cartoon come to life. For instance, in the old 'four color' process, there was exactly one shade of yellow, one of green etc. No variation. If you look ,you'll see that they did the same thing in the movie.
