Did you know that former FX guy and now director Scott Stewart has a Twitter? And that he’s Twittering from the set of his new film, Priest, which stars Paul Bettany as a warrior monk who battles vampires in a dystopian future? And that he’s announcing casting on that Twitter?

Now you do! And now you know that he has just announced that Christopher Plummer and Brad Dourif have joined the cast. While I love Dourif, he’ll appear in any old thing. Plummer, though – this guy brings a bit of gravitas! You last heard Plummer in Up, where he played Charles Muntz. Or I guess in 9, where he also does a voice.

Priest is shooting now near Los Angeles. I think I may be heading out that way in a couple of weeks, so maybe I’ll get a chance to meet Plummer himself.
