We’ve been telling you that ABC‘s new series 666 Park Avenue is dark, creepy goodness, but we have a lot to learn about the show, even after screening the pilot. Word is that we’ll be seeing a number of people moving in and “out” of the luxurious digs throughout the season.

TV Guide is reporting three of those names on the register: Aubrey Dollar, Mili Avital, and Mike Doyle. Ms. Dollar will be playing Annie, an obituary writer who wants to move beyond that niche, and whom we will be seeing in Episode 4. Mili Avital will be playing a woman who is longing for romance but has a dark secret. Ooo!

Mike Doyle is reportedly playing a character who is “a powerful adversary” to Terry O’Quinn‘s Gavin. He’ll debut in the second episode and will be a recurring character. Oh dear. We’re imagining having a recurring powerful adversary will make Mr. O’Quinn’s character pretty cranky. We can’t wait to find out!

666 Park Avenue, starring Terry O’Quinn, Dave Annable, Rachael Taylor, and Vanessa Williams, premieres Sunday, September 30 at 10/9c on ABC.
