After much anticipation (and blogosophere speculation), Lin-Manuel Miranda’s follow-up act to the sensation that is “Hamilton” has been revealed: Miranda will join British actress Emily Blunt on the big screen in a sequel to the 1964 Disney classic “Mary Poppins.” Fans will have to be patient, though — the film has a projected release of Christmas 2018.

Blunt will play the title character — the beloved nanny Poppins. Miranda’s role is an entirely new character, named Jack. “I was waiting until it was official. It’s official!” Miranda tweeted on Tuesday.

Much is expected from the sequel since the original film won five Oscars. Author P.L. Travers wrote eight books about Poppins, but only the first was made into a film.

Before getting into character as Jack, Miranda will head to the Tony Awards on June 12, where “Hamilton” is up for a record-breaking 16 awards.
