Jason O’Mara will join the cast of Marvel's Agents of SHIELD for Season 4 while the fate of Adrianne Palicki's Mockingbird is in more doubt than ever.

Deadline reports O'Mara "has joined the series as S.H.I.E.L.D’s new Director, playing a character whose Marvel roots go back to the 1940s" but no word on who that actually is. You may recall they jumped ahead a bit in time in the Season 3 finale.

“Bringing Jason into the mix as the New Director of S.H.I.E.L.D. forces everyone, particularly Coulson, to reevaluate their role in the Agency,” said Executive Producer and Marvel’s Head of Television, Jeph Loeb. “Jason has both the physical presence and acting dynamics that will connect with and challenge even the most loyal agent.”

O’Mara has a history with the network, having starred on their short-lived Americanized Life on Mars series as well as Grey's Anatomy. He's also been on the other comic book team before voicing Batman in a few Warner Bros. animated features.

Meanwhile, Palicki's time with the SHIELD team may be done. Remember how she and Nick Blood’s Hunter exited to star in their own spinoff series (Marvel’s Most Wanted)? That wasn't picked up, and now Deadline reports she's joined that Fox comedic drama created by and starring Seth MacFarlane and Scott Grimes. That one still doesn't have a name but sounds a lot like Futurama:

Set 300 years in the future, the untitled show — MacFarlane’s first live-action TV series — follows the adventures of the Orville, a not-so-top-of-the-line exploratory ship in Earth’s interstellar fleet. Facing cosmic challenges from without and within, this motley crew of space explorers will boldly go where no comedic drama has gone before.

I'm sure Palicki could easily do both jobs but here's what executive producer Jed Whedon had to say to TV Line at Comic-Con when asked about Bobbi and Hunter returning, “It’s definitely classified. But keep watching.”
