The Oscar-winning actress will voice the mythical character Karathen in the DC film, which is set to be released during the same time as the sequel to Andrews' 1964 classic.

Aquaman is welcoming a surprise star to the project as Julie Andrews is set to voice a key role in the upcoming Warner Bros. film, The Hollywood Reporter can confirm.

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.

Andrews' casting proves to be rather ironic as the DC pic will be released two days after the bow of Disney’s Mary Poppins Returns, the sequel to Andrews’ 1964 classic. Despite Dick Van Dyke reprising his role in the follow-up, Andrews will not be starring. Instead, Emily Blunt will take on the leading role of Poppins.

Over the years, Andrews has lent her voice to such animated projects as the Despicable Me franchise and Shrek Forever After in 2010.

EW was first to report the news.
