The Scorpion King franchise keeps getting more and more amazing.
The fourth one also stars Rutger Hauer, Michael Biehn, Barry Bostwick, Antônio Silva, and kickboxing legend Don "The Dragon" Wilson.
The Scorpion King: The Rock (WWE)
The Scorpion King 2: Randy Couture (MMA)
The Scorpion King 3: Dave Bautista (WWE), Kimbo Slice (MMA)
The Scorpion King 4: Roy Nelson (MMA), Royce Gracie (MMA), Antônio Silva (MMA), Eve Torres (WWE), Don Wilson
Soon, every combat sport star will have appeared in a Scorpion King film. I'm surprised Nathan Jones hasn't yet.
I assume the odd colon is to emphasize that it's a sequel, and not a film titled Fist 2 Fist 2.
Fist 2 Fist 3: Tokyo Fist.
