Now, four weeks later, the brothers are back to reveal that production has resumed on the fourth film with a cheeky Facebook post. Check out their post on the Avengers 4 filming below!

The currently-untitled feature will arrive one year after Avengers: Infinity War and will cap off Marvel Studios’ “Phase Three.”

The Avengers sequel sees Earth’s Mightiest Heroes teaming up with the Guardians of the Galaxy to take on Brolin’s Thanos and his Black Order.

Directors Anthony and Joe Russo, who return after Captain America: The Winter Soldier and Captain America: Civil War, are directing both Avengers: Infinity War and the untitled fourth film, which are being filmed back-to-back in Atlanta and are written by screenwriters Christopher Markus and Stephen McFeely. Both films will also be shot entirely with IMAX cameras.
