Brittany Snow revealed in an interview with Variety that her X co-star Kid Cudi has joined the cast of her upcoming directorial debut film September 17th

“I can’t really speak to it too much, except that Scott’s doing a part in the movie, so that’s cool,” Snow shared.

As for Cudi, he said Snow told him about September 17th while filming X, but he was never offered a role at the time. “I couldn’t believe that she wanted me in it,” Cudi said. “She had told me about the movie while we were on set [for ‘X’], but she never asked me to be in it. I was like, ‘Maybe she’s waiting to see how [‘X’] turns out.’ It’s gonna be awesome. Really great script.” 

According to Variety, September 17th was co-written by Snow and Becca Gleason (Summer ‘03) and follows a girl who was recently discharged from rehab amid food and body image issues. After meeting a man, she tries to navigate the line between unconditional love and a new addiction. 

The Pitch Perfect star said she observed X director Ti West “a lot” while filming, mentioning that one of her biggest takeaways was “the specificity of knowing the through line of what you want, and being really strong and clear in your convictions of it.” 

“I like to play around on set, but it lends itself really nicely when you know that your director has a complete handle on exactly what they want,” she continued. “I hope I can live up to what everyone else has been doing.” 

X, the slasher film starring Snow, Cudi, Mia Goth, and Jenna Ortega, hits theaters on March 18.
