Bryn Else Sandberg writes for the Hollywood Reporter, that Hollywood studios and unions have reached a return-to-work agreement with respect to COVID safety. Many of the provisions include guarantee of pay when forced into quarantine after a positive test. There are also provisions for rapid testing and rules for social distancing and safety. But generally if actors are tested regularly and reliably, they have more confidence they can work together.
Deadline has a similar story by David Robb.
The provisions should apply in other filming locations (Louisiana, Austin Texas, Atlanta, Vancouver, etc).
It would be interesting to see how COVID affects future screenplay pitch fests, if some of them would be virtual. It's Carlos Maza who always makes fun of the demand "Get back to work, baby!"
