Josh Hartnett
The former Hollywood heartthrob and more recent co-star of “Oppenheimer” (and the underrated show “Penny Dreadful”) is one of the new big names to join “The Bear.” In Season 3’s fourth episode, Hartnett plays Ritchie’s ex-wife Tiffany’s (Gillian Jacobs) affable fiancé, Frank, who wants to have a man-to-man “chat” with Ritchie, much to “Cousin’s” dismay.
