Max and Wu, two estranged brothers, are competing in the world’s most dangerous underground
fighting tournament, where powerful crimelords gamble and dictate who they fight and what
weapons are used. In this high-stakes bloodsport, one wrong move means certain death. The brothers must decide whether to play by the rules — or to cast their honor aside and team up against the syndicate controlling the system, risking everything to bring it down.

Directed by Chaya Supannarat, Gladiator Underground stars Ron Smoorenburg, Bear Williams, Brian Le, Andy Le, D.Y. Sao, Elliott Allison, Craig Ng, Geoffrey Giuliano, Apasiri Kulthanan, Selina Wiesmann, Michael March, Johnny Lee and Carl Piaf.

On October 17, 2025, Samuel Goldwyn Films releases Gladiator Underground to streaming platforms, via Bleiberg Entertainment.
