Josh Hartnett is in The Bear Season 3, Episode 4: VIOLET

Josh Hartnett joins “The Bear” as one of Season 3’s biggest guest stars. The actor plays Frank, the fiancé of Tiffany (Gillian Jacobs), the ex-wife of Richie (Ebon Moss-Bachrach). The two have a sweet but slightly awkward interaction after Richie drops off his daughter.

Frank seems like a good father figure to Richie’s daughter, Eva (as evidenced by the sloppy manicure he probably allowed her to give him), and he genuinely wants to have to have a good relationship with Richie. Frank apologizes to Richie for not warning him that he was going to propose to Tiffany, and he expresses interest in coming to the new restaurant.
