The Hamilton movie was shot over three days in June 2016, not too long before Lin-Manuel Miranda’s exit from the role to pursue additional projects, such as Moana and Mary Poppins Returns.
Broadway actors often do six shows a week when part of a major production such as Hamilton, and by the time the original cast said goodbye to the Richard Rodgers Theatre to make way for the new cast, much of the original cast had been playing their roles for a year and a half.
