Sean Penn won't return to work until cast and crew of Watergate series Gaslit get COVID-19 vaccines - 9Honey Celebrity

Sean Penn has set an ultimatum on the set of the upcoming Starz Watergate series Gaslit: either the entire cast and crew receive COVID-19 vaccines, or he's not returning to work.

Along with Robbie Pickering and Matt Ross, Mr Robot creator Sam Esmail — via his overall deal with UCP — and Chad Hamilton serve as executive producers under their production banner Esmail Corp.

Anonymous Content and Slate's Gabriel Roth and Josh Levin also executive produce Gaslit.
