Lin-Manuel Miranda may be ready for a little Chim Chim Cher-ee.

The 36-year-old Puerto Rican composer, lyricist, rapper and actor, best known for creating and starring in the Broadway musicals In the Heights and Hamilton, is in talks to join the Walt Disney Studios’ planned sequel to Mary Poppins. Emily Blunt is in talks for the lead role, played by Julie Andrews in the 1964 film.

Disney had no comment, but a source with knowledge of the project says the untitled film will connect with Mary’s charges, Jane and Michael Banks, now grown and with Michael’s own three kids in need of a nanny. Mary and her “lamplighter” friend Jack — kin to Bert the chimney sweep played by Dick Van Dyke opposite Andrews in the film — help the family rediscover the joy and wonder missing from their lives.

Miranda’s Disney ties already include the bar scene music for Star Wars: The Force Awakens and the score for the animated film Moana, coming in November.

According to the source, the new film will be set in Depression-era London and include material drawn from the seven Mary Poppins books writer P.L. Travers’ published between 1935 and 1988 following the initial novel.

Marc Shaiman and Scott Wittman will be composing original songs and an all-new score. David Magee is attached to write the screenplay. Rob Marshall is attached to direct.

Disney and Marshall are working with the Travers estate, and Mary Poppins composer Richard Sherman is reputedly aware and supportive of the project. Word of the talks first appeared earlier today in Variety.
