Fans of the Alien film franchise that started in 1979 with Ridley Scott’s classic will soon be returning to the world of Xenomorphs – and Isabela Merced (Father of the Bride) is joining in the sci-fi horror fun. The film will be made under Scott’s Scott Free production company.

Merced has been cast in a new Alien movie that will be directed and co-written by Uruguayan filmmaker Fede Alvarez (Don’t Breathe). The film is also co-written by Alvarez’s fellow Uruguayan filmmaker Rodo Sayagues (Don’t Breathe 2). Merced joins Cailee Spaeny (Mare of Easttown), who was already announced as part of the new movie.

“Don’t even know what to say,” Merced wrote on social media. “Don’t even know what I would say if I could say … I’M JUST SO EXCITED.”

Little is known about the new project, but Deadline is reporting that the vicious aliens known as Xenomorphs will return to play a main role in the movie, which will be the ninth in the franchise. The last movie was 2017’s Alien: Covenant, which served as a second prequel to the series after 2012’s Prometheus. Scott returned to direct both those films.

Merced was last seen playing the iconic role of Juliet in the Hulu original film Rosaline, which tells the story of the young woman who was romantically involved with Romeo before he met Juliet. She will next be seen in Turtles All the Way, a film adaptation of John Green’s novel of the same name. Some of Green’s other novels that have been made into movies are The Fault in Our Stars, Paper Towns and Let It Snow, the latter of which Merced also starred in.

Isabela Merced also recently shot the Marvel superhero movie Madame Web, which stars Dakota Johnson (Cha Cha Real Smooth) in the title role.
