Film industry worker here (union lighting tech. I'm not on strike but I'm not working due to the shutdown). Yes, the actors are still on strike so productions won't be able to resume (although a lot of pre-production will be able to). The hope is though, that the AMPTP cutting a deal with the WGA will both be a sign that they're willing to end the industry shutdown in general, and also that the deal with the WGA can provide a bargaining pattern to make the negotiations with SAG-AFTRA resolve faster. That's just a hope though, only time will tell if it's true.
