If only someone in the steelbook universe would say to themselves, "Selves, instead of pop art or cut and paste art, let's always do the movie poster art", I would be happy. Sure, they could throw in some mini lobby cards, but I'd be happy with the poster art.
Perhaps they went this way because the original poster art had been done. But if they were doing to shelve that idea, which they did, I would have much preferred Curt and the Pharoahs on the front, Steve and Laurie on the back, and a collage of John Milner, Carol, Toad and Debbie on the inside art. But that's just me.
