For historical footage, I could see some use cases. For cinema, I don't know why you'd want to do this. < 60 fps playback of video that was shot at < 60 fps looks just fine. Even if the interpolation was perfect, what's the benefit?

Personally, I love 60fps+ videos. They just seem more "realistic" to me, as if the person moving on the screen was right in front of me. Ordinary 24fps is okay, but there's a certain "not real" feeling I get while watching it. It's like playing a videogame that stutters all the time.
