All I'd say is as long as you do it safely (get checked for the virus first, and have all crew wearing masks, washing hands and staying apart as much as possible etc etc) then business has to go on. Actors need to be tested first, and then when not on camera should wear masks. The virus hasn't changed, it's still out there. You can still film for sure, you've just got to be guided by the science of the virus and nothing else.
