We may have the official start of filming date for the newest Star Wars live action TV series via a leaked image from the Star Wars Leaks sub-reddit.
Redditor Smoove4254 pulled an image from productionlist.com, an industry job board that lists all in production movies and shows, showing a Shoot Date of June 1, 2020 for the upcoming Cassian Andor series.
There is little further information given on the post, but given the required membership to see posts like this, it is likely a legit date.
