this was made purely because of Gladiator
Funny isn't it a film like Gladiator which was seen as a big gamble (long dead genre last popular in the 50s, director who no had a hit in years, unknown star etc) becomes an award winning megahit and then spawns similar themed movies like this and others .. (in fact Gladiator itself was probably influenced by the success of Braveheart)
Like after Star Wars every movie after was a SciFi extravaganza (even 007).. or when XMen/Spiderman spawned all the Marvel/MCU movies and made DC and others rejuvenate their stuff into shared universes..(unlike Superman which didn't do much for other comic book films back in the 70s/early 80s,, or Batman 89 which instead of spawning other superhero films influenced similar retro noir stuff to get made like Dick Tracy, The Rocketeer, The Shadow)
You'd think studios filmmakers would think 'well we don't wanna be seen to be copying so and so.. so we'll do something else' and actors would be 'hey I don't wanna be seen be copying Russell Crowe!'.. but nope
