Colin Firth joins Emily Blunt in ‘Mary Poppins’ sequel

Meryl Streep and Ben Whishaw also have key roles in 'Mary Poppins Returns'

Colin Firth has joined the cast of Mary Poppins Returns.

He will play William Weatherall Wilkins, president of Fidelity Fiduciary Bank, in Disney’s Mary Poppins sequel, Variety reports.

Emily Blunt has been cast as Mary Poppins, with Hamilton creator Lin-Manuel Miranda co-starring as new character Jack, a street lamplighter.


Meryl Streep will appear in a supporting role as Mary Poppins’ cousin. Meanwhile, Ben Whishaw and Emily Mortimer are playing grown-up versions of Michael and Jane Banks, the children Mary Poppins once looked after.


Rob Marshall, who specialises in film adaptions of Broadway musicals, is directing. Tony-winning composer Marc Shaiman is writing the score and collaborating with Scott Wittman on new songs for the film.

“I am truly humbled and honoured to be asked by Disney to bring PL Travers’ further adventures to the screen,” Marshall said when the film was announced.

“The iconic original film means so much to me personally. And I look forward to creating an original movie musical that can bring Mary Poppins, and her message that childlike wonder can be found in even the most challenging of times, to a whole new generation.”

Mary Poppins first appeared in a 1934 book by PL Travers. Seven further more books about her adventures published between 1935 and 1988.
