It's been confirmed today that Supernatural and The Walking Dead star Lauren Cohan was cast in Batman v Superman: Dawn of Justice in a top secret role, and we know who she'll be playing! It's a character who is vital to Batman's story, so read on for details...

As you can see from the Tweet below, IMDb (before you bring up the fact that anyone can edit the cast lists on the site, I've NEVER seen their official Twitter account mention one of those unconfirmed additions) has confirmed that Lauren Cohan is playing Martha Wayne in Batman v Superman: Dawn of Justice. While it's a little disappointing that The Walking Dead star hasn't been chosen for an ongoing role in these movies as someone like Batgirl, this is still a pretty cool bit of casting news. The trailer previously revealed that Watchmen's Jeffrey Dean Morgan - who will be getting to know Cohan very well on the Atlanta set of her AMC series in the coming months when he takes on the role of Negan - is playing Thomas Wayne and that we're getting another Bruce Wayne origin story. What do you guys think about Lauren Cohan playing Batman's mother?
