UPDATE 2:50 PM PT: Deadline has clarified that "Scarlet" is in development as a TV series at Cinemax, rather than HBO, as previously reported. Cinemax is under the same parent company as HBO, as part of TimeWarner Inc.
According to Deadline, "Scarlet" was "on hand" at the ATX Television Festival in Austin, where Bendis made the announcement.
Bendis reportedly said, "I do a book called Scarlet which is soon to be announced also in our universe of television. Not announced yet, but HBO."
The "Alias" creator said the project is still in its infancy, and that "...the team around it...will be announced as soon as all are on the same page."
If the project moves forward, "Scarlet" would be Bendis' third project currently on the small-screen, alongside PlayStation Network's "Powers" (also based on an Icon series) and Netflix's "Jessica Jones" series.
First published under Marvel's creator-owned Icon imprint, "Scarlet" follows a rebellious young Portlander named Scarlet Rue who sparks the second American Revolution.
