It's hard to know what to compare this to; there's nothing quite like it. I see some describe it as "body horror", so we might pull in David Cronenberg. But this is a warmer and more fun film than something like
Videodrome, a good movie in its own way.
Ken Russell never did anything else similar. I've reviewed a few of his other films:
I have the new UK DVD of
The Devils on hand but am waiting for a good moment. It has a fearsome reputation and I've never seen it.
I remember hearing that Russell had both pre- and post-acid work, but googling I'm not finding any commentary on that, so maybe it was just a story. There are several biographies and I should get one.
