The series features several real-world MMA personalities playing themselves, including Ciryl Gane, Georges Saint-Pierre, Jon Jones, Anissa Meksen, Taylor Lapilus and Morgan Charrière.

Filming of season 1 began in early June 2023 in Paris and wrapped on September 29, 2023.

The show was written by Sylvain Caron, Nicolas Laquerrière, Elsa Vasseur and Alain Moreau, and directed by Franck Gastambide and David Krespine, with Gastambide also starring as Boss.

Just two weeks after season 1 premiered in November 2024, Netflix announced that La Cage would be renewed for a second season.

The series received mixed reviews, holding an average rating of 6.4/10 based on 400 votes on IMDb.

Critic Marine Pérot of Les Numériques gave the show just one star out of five, criticizing its clichéd plot centered on stereotypical characters like the outsider fighter, the angry antagonist and the reluctant coach.

Arnaud Hallet of Les Inrockuptibles wrote a scathing review, describing the show as a 'ChatGPT-labeled shipwreck' that produced a flat and anemic result from the otherwise raw material of MMA.
