Fun fact (seen on Wikipedia): in Sabrina, a movie from 1995, there’s an Apple prototype. It’s a prototype of the Spartacus, the 20th-anniversary Mac. According to Wikipedia, it was loaned by Apple, almost two years before its release.
You can’t see it very well because I don’t have the movie on Blu-ray, but this model has a transparent window on the optical drive door, while the door of the model sold in stores is opaque.
Note that the model seen in Batman & Robin is also apparently a prototype; the mechanism of the optical drive seems identical.
