Warning: Contains major spoilers for The Bear Season 4.

The Bear is a show that loves its famous guest stars, and Season 4 is no exception.

This season sees a mixture of new and returning faces, with some of the big names we saw in Season 2's "Fishes" episode making another appearance, and other new and very famous faces joining them for an episode or two.

From Francie Fak finally being unveiled to a recurring role for a very famous director, we've broken down all the Season 4 guest stars below.

New guest stars

Brie Larson as Francie Fak

In the buildup to the wedding of Tiff (Gillian Jacobs) and Frank (Josh Hartnett), it's apparent that we may finally get a glimpse of Francie Fak — a character that Natalie (Abby Elliott) has long had beef with, even though we're never told why. Sure enough, Francie is indeed at the wedding in episode 7, and she's played by none other than Captain Marvel herself, Brie Larson. The two of them rage at each other for a while, then ultimately make amends. (It's still not entirely clear why they fell out in the first place.)

Rob Reiner as Albert

Rob Reiner, legendary director of two of the all-time greatest Stephen King adaptations (Stand By Me and Misery), has a recurring role in Season 4 as Ebraheim's (Edwin Lee Gibson) business mentor, Albert. Albert helps Ebraheim come up with a plan to franchise The Beef sandwich shop by expanding into new territories.

Danielle Deadwyler as Chantel

Danielle Deadwyler (Till, Station Eleven) has a starring role opposite Sydney (Ayo Edebiri) in episode 4 (the same episode Edebiri co-wrote with Lionel Boyce), playing a hairdresser who's also a longtime friend of Sydney's.

Kate Berlant as an AI-Anon member

Comedian Kate Berlant only has a short scene at the start of episode 5, where she plays a member of the Al-Anon group that Carmy attends. But she absolutely crushes the monologue she does have, which is about her experience of leaving her brother — a recovering addict — at home by himself while she has to go out of town.

Alpana Singh as a sommelier

In episode 2, budding sommelier Sweeps (Corey Hendrix) visits a restaurant to get a wine lesson from another sommelier. The twist is the woman in question is actual real-life sommelier and restauranteur Alpana Singh.

Returning guest stars

There's no John Cena this season, but there are a lot of returning guest stars, many of whom appear at Tiff and Frank's wedding in episode 7.

Sarah Paulson as Michelle Berzatto

Carmy's cousin Michelle (Sarah Paulson), who let him stay with her in New York after that nightmarish Christmas in Season 2's "Fishes", attends Tiff's wedding. She can't stay long, but she's in a few scenes with Tiff and the rest of the family.

John Mulaney as Stevie

Michelle's partner Stevie (John Mulaney) is in top comic-relief form in episode 7, helping the Faks pitch one of their quirky business schemes to Pete (Chris Witaske) and taking part in an amusing exchange with Syd and Carmy about the latter's time in New York.

Bob Odenkirk as Uncle Lee

One of the most moving scenes in episode 7 comes courtesy of a less-fiery Uncle Lee (Bob Odenkirk), the same man who had that horrendous argument with Mikey back in the "Fishes" episode. This time Lee finds Carmy hiding out in the kitchen, and shares some poignant words about the things Mikey used to tell him about his brother.

Jon Bernthal as Mikey Berzatto

Speaking of Mikey, Jon Bernthal is also back in Season 4, appearing in an opening flashback with Carmy that reveals where the idea for The Bear's name came from.

Jamie Lee Curtis as Donna Berzatto

Donna (Jamie Lee Curtis), the troubled and terrifying matriarch of the Berzatto family, has several key moments in Season 4. She's briefly at the wedding in episode 7, where she shares a surprisingly tension-free conversation with Sydney — and then she has a large role in episode 9 opposite Carmy, trying to make amends for her past behavior.

Will Poulter as Luca

Pastry chef Luca (Will Poulter), who trained with Marcus (Lionel Boyce) back in Denmark in Season 2, has a recurring role in Season 4 as a stage at The Bear — basically, he's a glorified unpaid intern. As such, Luca helps Marcus with the desert station.

The Bear Season 4 is streaming now on Hulu.
