Ruffalo, Edwards co-creating TV series

Mark Ruffalo and Anthony Edwards have signed to co-create and possibly star in an upcoming Showtime drama.

According to Deadline, the actors will also executive produce the show, reportedly about partners running a crisis management firm.

However, both actors's schedules could keep them from starring in the forthcoming series.

Ruffalo and Edwards were said to have come up with the idea for the show on the set of the David Fincher film Zodiac.
