Midge's talent manager and friend, Susie, is played by Alex Borstein — who also appeared in Gilmore Girls in several different roles. Much like the disgruntled harpist, Drella, whom Bortsein plays in season one of Gilmore Girls, Susie doesn't mince words or mess around. But in the scope of Mrs. Maisel, we'd say Borstein carries herself a bit more like Luke Danes; she's perplexed by frippery, doesn't understand feminine social norms, and rocks the hell out of a hat. (Not to mention her affinity for diner food.)
As a bonus casting nod . . . Bailey De Young, who plays Midge's friend Imogene Cleary, also appeared as one of the 30-something gang in Netflix's Gilmore Girls: A Year in the Life!
