The Independent Film Channel has greenlit a trio of shows — an animated show from Bob Balaban, a Christopher Guest-style look at an indie film studio and a revived “Greg the Bunny” — for this year’s lineup. The projects — all of which feature some sendup of IFC as a network — will debut back-to-back in a one-hour block at 10 p.m. during IFC’s “Film Fanatic Fridays” beginning Aug. 19. “The Festival” is a six-part, half-hour parody told from the perspective of fictional documentarian Cookie, recruited by IFC to shoot a film about Rufus, director of “The Unreasonable Truth of Butterflies.” “Hopeless Pictures,” from writer-director-producer Balaban, is a cartoon about the head of a dysfunctional indie film studio, voiced by Michael McKean. “Greg the Bunny” takes off from the cancellation of Greg and Warren the Ape’s Fox sitcom. To pay the bills, the pair has been reduced to making film parodies for IFC.
