It never got proper distribution in the US, I suspect due to studio politics with a new studio head buring a project they didnt like similar to Big Trouble In Little China but its much better remembered in Europe.
I'm guessing having an aging UK thesp in John Neville as the lead didnt help but its great to see him get such a chance and run with it rather than just having supporting roles. For all the cost overruns as well its a film were you can absolutely see were the budget went, honestly I think it maybe impossible to make such a film anymore with pratical FX/Set work on this scale, would cost $300 million or something insane.
