It will depend on the stage of the production. Pre-production could be still on track by getting the personnel, tools and locations. Just forget about writers and actors schedules, so it can be in the air, and even be postponed as a lot of things must land the same dates.

If they’re on post production, special effects and editing is fine. Reshoots, specially with actors, won’t happen.

I assume they’ve not even begun pre production, so it’s safe to say that, as most tv series and movies, will be postponed.
