We shot in Santa Barbara, which was absolutely beautiful, and working with Bruce Weber has definitely been one of the great experiences I’ve had. Plus all of the actors were a lot of fun!” said Rabe. “Glee” star Artist said he just wrapped a film called “White Bird in the Blizzard” and “Grown Ups 2” star Sage just finished “Townies” with Zac Efron. She also starts filming her new NBC series, “Crisis” next month.
