Marshall and another of the newcomers, Patterson, will appear alongside Teyana Taylor and Zach Cherry in the upcoming Kevin Hart movie “72 Hours” on Netflix. Patterson, a standup comic, is also a regular on Tony Hinchcliffe’s comedy podcast “Kill Tony.”

Slowikowska has appeared in Shane Gillis’s Netflix workplace comedy “Tires” and the FX horror mockumentary series “What We Do in the Shadows.”

Brennan, a standup comic, was selected as a New Face of Comedy at the Just for Laughs comedy festival in Montreal in 2023 and has performed on “The Tonight Show Starring Jimmy Fallon.”

And Culhane is a regular on Dropout, a comedy streaming service. He has also performed with the Upright Citizens Brigade in Los Angeles. Culhane and Slowikowska have each racked up tens of millions of views on TikTok, with some posts having gone viral.
