It was an extremely educational Zoom call and I was impressed to find out they had just received an Emmy Award trophy for their work on their groundbreaking projects.įull disclosure: When I pressed him, Alex declined to comment on their involvement in the Book of Boba Fett at this time, mentioning that the production company will probably make an explanatory ‘making-of piece’ like they did for Mandalorian.
