The Eagle of the Ninth film and Centurion are totally different stories, the director of Centurion, Neil Marshall, has said. Rosemary Sutcliff’s book is the basis only for the film of the same name. Asked if he found it ‘fortuitous to be releasing Centurion given the revival of the swords and sandals movie and with The Eagle of the Ninth and Clash of the Titans among others coming out, he said:
There does seem to be this year, but it is just a weird coincidence because nobody is hopping on anybody else’s bandwagon. You don’t try and do that… you want to be the only one in the marketplace, not one of many. Ourselves and Eagle of the Ninth deal with the Ninth Legion but are totally different stories. They’ve been running in parallel for the past six years and it was pure chance as to which one got into production first. As it happened, we did and they quickly followed, but we’re out first. If there’s an appetite for these movies, then great… I just hope that people see Centurion because the tone of it is very different from anything else that’s out there.
