Yvonne Orji has been cast in the upcoming film, Spontaneous, from Awesomeness Films.
Piper Perabo and Rob Rob Huebel were also announced Wednesday.
They join the previously-announced cast members including Riverdale actress Hayley Law, Charlie Plummer and Katherine Langford, who toplines the film.
The film's description: Mara Carlye (Langford), whose life is forever changed when students in her senior class literally explode for no discernible reason. As students continue to pop like blood-filled balloons and the town descends into both chaos and apathy, Mara and her friends stay close together as they await possible combustion – wondering what part of life is worth living if it might end suddenly.
Orji will play Special Agent Rosetti, "who is investigating the combustions taking place."
The actress, who stars in Insecure, will also appear in Night School with Kevin Hart and Tiffany Haddish.
THR first reported the casting.
