Bad news: Marisa Tomei will not be starring in Aaron Sorkin's HBO pilot about life in the cable news world, More As This Story Develops. Good news: Emily Mortimer might!

Deadline reports that Tomei ultimately wasn't interested in doing television, so producers moved on to Mortimer. Judging from her prior work (especially in Lovely And Amazing, where she bears her, er, soul), this could be a match made in walk-and-talk heaven.
