I admire their ability to get paid for this!

First and foremost: the Cyclops wasn't a Roman legend, it was Greek! (Check any decent production of Homer's "Odyssey".)

Eric Roberts was the best-known name in the cast, and therefore the first name mentioned in all the promo advertising. However, with what little screen-time Mr Roberts got, even he could not have saved this turkey. They wrote the Emperor Tiberius character as if they'd never heard anything about the real man beyond his name. They had Tiberius completely under the sway of his evil counselor.

The CGI Cyclops effect was just plain dumb! It has to be seen to be (dis-)believed. — And I don't recommend it.

All in all, I found it a complete waste of time and the electricity it took to power my TV.

I have to admire the film-makers' ability to get paid for this.
