Yes, a few 35mm films had 4 track mag audio. The only one I can think of off the top of my head was Fantasia.

I think I've seen 2001, maybe Lawrence of Arabia, and perhaps one or two of the other big epic movies of that era on 35mm with mag sound.

Even by the late 70s, decent prints were getting hard to find though.

I would have thought Wikipedia would have a list but it's not obvious if they do.
