It looks like the Marvel Studios machine is revving back up. In addition to signs that Shang-Chi and the Legend of the Ten Rings will resume production in Australia soon; the Disney+ series look to be resuming production next month.
According to a Facebook post by the Tampa Bay Comic Con, Paul Bettany had to cancel his appearance due to being called back to resume WandaVision filming in July:
When production of the shows and movies shut down a couple of months ago, WandaVision was nearly complete and post-production continued remotely during the shutdown. If this report is correct and they’re going back for filming in July to complete the series; it should mean they’d be able to at least hit the December date for WandaVision and any rumors of them splitting the six-episode show into two parts seem to be debunked.
