A brand new episode of Disney Gallery: The Mandalorian Season 2 will drop on August 25th. This special episode will focus solely on the making of the incredible season 2 finale.
While nothing is confirmed yet, it is highly likely that this episode will be heavily focused on the Luke Skywalker reveal and all that went into making that happen. That means that we will probably get to Mr. Mark Hamill talking about his experience on the Mando set and what it was like to reprise the role of Young Luke Skywalker.
