Heading back to The League in December are guest stars Seth Rogen (porn auteur Dirty Randy, on December 13) and Jeff Goldblum (Rupert Ruxin, in the hourlong season four finale on December 20). Goldblum “will insert himself into a marital situation between his son (Nick Kroll) and daughter-in-law (Nadine Velazquez),†while Rogen’s reprising his role for a Mayan-doomsday episode. Bob Odenkirk will also turn up before the season wraps. All good things.
