Quote Quoting Rowland (view post)
Regarding Gordon, I'd recommend King of the Ants, Dagon, and The Pit and the Pendulum as some of his undervalued efforts.
I haven't seen his "middle movies." I.e.

Robot Jox
The Pit and the Pendulum
Fortress
Castle Freak
Space Truckers
The Wonderful Ice Cream Suit

Probably start out with Pit and Castle Freak.
