You were talking about A Knight's Tale in that post, which isn't with the legion...But what does Gaius Julius Mento have to do with it? He was a bureaucrat and never left Rome. I never heard of a Septimus Sulla emperor, either. And Tartarus? It belongs to the Greek Mythology and has nothing to do with either of them.
I'm sure Arthur must have fled when he saw the script, thinking he was on the wrong set.
I'd be fine with a twist, but this is a little too burlesque for me. It feels like a lack of imagination. To each their own, though.
The Roman one is more far-fetched, certainly.
