The directors for the series were officially announced and include Dave Filoni (Star Wars: The Clone Wars, Star Wars Rebels) who will direct the first episode.
The Mandalorian will be executive produced by Jon Favreau, Dave Filoni, Kathleen Kennedy, and Colin Wilson.
According to the site, the gun just might be the same one used by Boba Fett in the much maligned Star Wars Holiday Special.
Though, admittedly, it’s a pretty nice Easter egg for Star Wars fans and shows that Favreau has done his homework.
