I came across an interview with Scoot McNairy who has guest-starred on Bones twice and likes to work on independent films. When asked about upcoming projects, he mentioned Amy! Quote is below; no further details as of yet, but I shall keep you guys posted.
Q: Ok, so tell us what you’re currently working on. I know you have several movies in production and things are busy for you.
McNairy: …And I have another film that I’m producing that I’m doing with Amy Acker who was on Angel, Alias and now is in Dollhouse.
Q: You’re going to be everywhere, aren’t you?
McNairy: Well, I’m trying. [laughs] I’m just going to keep doing what I’m doing, making independent films and doing my thing.
