Entertainment news today mixed remembrance, reinvention and prestige. Fans are mourning Grizz Chapman, the beloved “30 Rock” actor who brought warmth and comic presence to the role of Grizz across the sitcom’s run, after reports of his death at 52. In a very different TV turn, Stephen Colbert resurfaced almost immediately after his CBS farewell by guest-hosting the quirky Michigan public-access show “Only in Monroe,” joined by an improbable lineup including Jack White, Eminem, Jeff Daniels and Steve Buscemi — a fittingly offbeat coda to “The Late Show.” On the legal front, Michael Wolff’s attempt to head off a threatened defamation suit from Melania Trump was thrown out by a federal judge as an improper preemptive move. And at Cannes, Cristian Mungiu’s Norway-set drama “Fjord” claimed the Palme d’Or, confirming the Romanian director’s enduring status as one of festival cinema’s major voices.
