Nicholas Galitzine is stealing hearts in every movie he takes part in and it seems like 100 Nights of Hero may be no different. The film, based off the graphic novel of the same name by Isabel Greenberg, sees Galitzine, who has packed on some muscle after filming the upcoming He-Man movie called Masters of the Universe. The clip that was released on Monday is just a teaser trailer, so it's just a snippet of what audiences can expect. But nonetheless, Galitzine steals our attention every time. The movie is set to be an adaptation of Greenberg's book that follows two women, Cherry (Maika Monroe) and Hero (Emma Corrin) in love. Cherry is told that she must become pregnant within 100 days and if she doesn't, she "not see next spring."Galitzine plays houseguest Manfred, who seems to become enamored with Cherry after being ordered to bear a child, and he seems to be up for the task. In the trailer, we get a glimpse of a shirtless, bloodied, Galitzine holding up a stag's head and smiling. He and Monroe's character also share an intimate moment for a split second.Rounding out the star-studded cast is Charli XCX, who appears to be playing an instrument, Richard E. Grant as Birdman, Safia Oakley-Green as "kiddo," Amir El-Masry as Jerome, and Felicity Jones as "Moon/The Narrator."This also sets the stage for Charli to take some time away from music after having a huge moment with Brat last year. She appeared as herself in Benito Skinner's Overcompensating, but in addition to this she is lined up for multiple projects including the Pete Ohs-directed Erupcja, a film called I Want Your Sex directed by Gregg Araki, and a movie she will produce and star in called The Moment at A24.100 Nights of Hero premieres on September 6 at the Venice Film Festival, followed by a theatrical release on December 5.
