Hollywood Romans -- New Feature Film about...

[Robert Vermaat]

For a proper Roman film, two criteria must be met: first, there have to be gladiators involved.

No problem, any 'Roman' movie can start with a gladiator scene, underlining the brutality and perfidity of the Romans.

Second, there has to be at least one blue-painted sort-of-Keltic guy, preferably several. The first shouldn't be a problem, since of course Crassus's legions naturally would have toted along a pack of gladiators while invading the Parthian empire. The Kelt might present more of a problem. Maybe they can score a twofer with a blue-painted Keltic gladiator. Or several.

With one addition, the 'painted' guy MUST be yapping our ears off about the FREEEDOMM of his people, which is why he is fighting Rome and it's 'baaad' officials. (And which is the reason for him being even more brutal than the Romans, of course).
They can use a painted guy and make him a Scythian ally of the Parthians, or something. Parthians (Parni) were themselves very similar to Scythian peoples so that would not be very odd (leaving the fact aside that Scythians were not painted but who's counting anyway?).
