ComingSoon.net sprak met producent Mark Canton en vroeg hem naar de geplande 300 prequel Xerxes. Canton wist te vertellen dat Zack Snyder, regisseur van het origineel, nog lang geen zekerheid is voor de prequel.
"I can't say. I mean, he's got 'Superman.' He's busy. We're busy. I don't think we're going to wait two years. But we'll work together with him and figure out who the filmmaker should be if he doesn't direct it."
"We're taking a lot of time because Zack really did create something that goes in the time capsule. We want to be faithful to the first one, but we don't want to do a conventional sequel. But we're getting close."
We weten dat twee personages uit 300 te zien zijn in de graphic novel van Xerxes, namelijk Ephialtes, de Spartaanse verrader en Leonidis, in de film gespeeld door Gerard Butler. De prequel staat gepland voor 2013.
