If you loved Fortress, try Robot Jox
A bridge between a film you've already seen and one most people haven't. Robot Jox has roughly 4.9× fewer votes than Fortress — it's a deeper cut, not a mainstream recommendation. Here's what they share, and what the second one does that the first one doesn't.
What they share
Both films are directed by Stuart Gordon, and they sit in Action / Science Fiction territory. If that's the register that drew you to Fortress, the second film will land in a comparable space — through a different lens.
What Robot Jox is
You pilot a massive machine in gladiatorial contests over geopolitical turf. But a critical malfunction injures hundreds in the stands. It changes everything. Gordon's practical effects are a throwback. The film lingers in the mind like a half-remembered cartoon.
