He is portrayed by Peter Mullan who also played Corban Yaxley in Harry Potter and the Half-Blood Prince and Harry Potter and the Deathly Hallows Part 1.
After finishing a recent mission and saving his nephew, Hercules and his men are celebrating and drinking at a tavern when they are approached by Ergenia, on behalf of her father, Lord Cotys, who wants Hercules to train the armies of Thrace to defend the kingdom from bloodthirsty warlord Rheseus. Hercules accepts after he and his men are offered his weight in gold, and the band is welcomed to Thrace by King Cotys and General Sitacles, leader of the Thracian army.
Then Hercules and Sitacles confront Rheseus and his soldiers on the battlefield before Mount Asticus.
He (Hercules) is attacked by Sitacles and Hercules got into a short and violent fight; Sitacles is then stabbed by Iolaus.
- Though Lord Cotys was the main villain of the film, Sitacles did most of the action and was more threatening towards Hercules and his team than Cotys.
