Julie Andrews is voicing a key role in Warner Brothers’ upcoming film, Aquaman.
The Oscar-winning actress will voice the mythical character Karathen, described as being a creature holding the key that can assist in Arthur Curry’s (Jason Momoa) mission to create peace between Atlantis and dry land.
The DC film will be released two days after Disney’s Mary Poppins Returns, the sequel to Andrews’ 1964 film.
Dick Van Dyke is reprising his role in the new film, but Andrews will not be starring.
Instead, Emily Blunt will take on the leading role of Poppins.
The role will mark Andrews’ first role in a film in nearly a decade. Over the years, the actress has lent her voice to animated projects such as the Despicable Me franchise and Shrek Forever After in 2010.
EW was first to report the news.
