As studios debate how to handle COVID-19 vaccine resistance, the Biden administration is moving forward with its own mandates that are pushing Hollywood to toe the line.

We’re really only considering those who are vaccinated,” one prolific producer tells The Hollywood Reporter about COVID requirements for features they’re working on. Another producer, gearing up for a big studio production, concurs: “We will not engage with anyone who is not vaccinated.” But enforcement will be key as studios ensure that workers, from talent to crew, show proof.
