Wow. This is one hell of a poster! Not sure if this is the official poster (it looks like it). Starz will also be releasing official photos soon so those will be going up shortly.
Pictured is Batiatus, Lucretia, Gaia (Lucretia's long time friend) and the Champion of Batiatus' Ludus Gannicus
A true physical specimen, fearless in the arena and possessed of a thirst for the fleeting pleasures of life, Gannicus is the gladiator a girl’s mother doesn’t want her to bring home. Newly promoted to the top position at Batiatus’s ludus, Gannicus is best friend to Oenomaus and his wife Melitta, forming an unlikely triangle of loyal friendship
Many thanks to Roland for the news!
