Alison Brie is to play villain Evil-Lyn in the 'Masters of the Universe' movie.

The 'Mad Men' actress has secured an important role in the live-action flick from Amazon MGM and Mattel Films.

Alison, 41, joins a cast that includes Nicholas Galitzine in the lead role of He-Man and Camila Mendes as Teela, the captain of the royal guard and the possible love interest.

'Bumblebee' helmer Travis Knight is directing from a script by Chris Butler although plot details are yet to be revealed.

'Masters of the Universe' was introduced to the world via action figures in 1982 and focused on the battle between the heroic He-Man and the evil Skeletor.

The animated series 'He-Man and the Masters of the Universe' premiered the following year and several other film and TV adaptations have followed since as the franchise is still going strong.

The movie is slated for release in June 2026 after enduring a two-decade journey to the big screen.

It was axed by Netflix last year due to budget concerns while directors John Stevenson, Jon M. Chu and McG have all been attached to the project since 2007.

Julie Rapaport, head of film production and development at Amazon MGM Studios, said in a statement following Galitzine's casting: "We're thrilled to bring the beloved 'Masters of the Universe' to life and couldn't be more excited to announce the immensely talented Nicholas Galitzine as our He-Man.

"Joining forces with director Travis Knight, Mattel, and Escape Artists, this reintroduction of the character and his universe will be an epic film that will delight audiences from here to Eternia."
