Plenty of information about Fox's upcoming X-Men-inspired drama series has been revealed in the past few weeks. We now know that it will include some notable X-Men characters and that the pilot will be directed by frequent X-Men film director Bryan Singer. Now, a new listing on My Entertainment World clues us in to when the pilot will begin production.

The listing, which you can see below, states that the pilot episode of the still untitled "X-Men" drama series will begin on March 13 in Dallas, Texas. The listing still has the series' old title, "Hellfire," from back when the Fox series had different creators involved and was going to focus on the Hellfire Club.

This X-Men series comes from "Burn Notice" creator Matt Nix and will focus on two ordinary parents who discover their children possess mutant powers. On the run from the government, they join with an underground network of mutants and must fight to survive. In a recent interview, Nix confirmed that there will be some known characters in the series.

“The only thing that I would say is that it’s a … some of those things are slightly up in the air, but the fact that it’s a question I can’t answer tells you something," said Nix. “Suffice it to say it’s a show that contains some characters that fans will be excited about. I can’t talk about specifics, but it’s not like there are no X-Men in it.”

That separates it from the other X-Men television series debuting this week on FX, "Legion." That series stars a character from the comics, Professor X's son David Haller, but so far the rest of the cast appears to be all original characters created for the FX TV series. Nix's X-Men series will reportedly hew closer to the comics, while most likely not sharing a universe with the feature film franchise.

Along with Nix, X-Men film franchise veterans Lauren Shuler Donner, Bryan Singer and Simon Kinberg are set to serve as executive producers, as is Head of Marvel Television Jeph Loeb. Unlike Fox’s X-Men films, which are produced completely outside of the auspices of Marvel Studios and its parent company Disney due to a longstanding rights deal, Marvel Television is a credited producer on live-action X-Men shows, including “Legion," along with 20th Century Fox TV.
