David Fincher’s new film The Killer premiered at the Venice Film Festival this weekend ahead of an October theatrical release. (It’ll debut on Netflix on November 10.) In addition to a score by longtime collaborators Trent Reznor and Atticus Ross, the movie includes a bunch of songs by the Smiths — apparently the soundtrack of choice for the film’s contract killer main character, played by Michael Fassbender.

As Indiewire reports, Fincher talked about the Smiths-heavy soundtrack in a press conference at the festival. Songs used in the movie include “How Soon is Now?,” “Bigmouth Strikes Again,” and “I Know It’s Over.”

“The Smiths were a post-production addition because I knew I wanted to use ‘How Soon is Now?’ and I love the idea of that song specifically as a tool for assuaging his anxiety,” Fincher said. “I liked it as a meditation tape, I thought it was amusing and funny.”

“I don’t think that there’s a library of music by recording artists that have as much sardonic nature and wit simultaneously [as the Smiths],” Fincher continued. “And we don’t get an awful lot of access to who this guy is. I thought through his mixtape it would be amusing, that that would be our window into him.”

Here’s the recently-released teaser trailer for the movie:
