It's being said that Fox is developing an X-Men series for TV.
According to Bleeding Cool, who also nabbed the scoop about the Supergirl TV series, Fox is deep in development in the live-action X-Men TV series.
No further details are mentioned, but obviously Fox would want to capitalize on their X-Men franchise, similar to what both Warner Bros. and Marvel are doing for their own comic book properties.
Fox owns the rights to the X-Men characters as well as the Fantastic Four.
