Kate & Rooney Mara Cast in Werner Herzog Movie via Old-School Letter

Hollywood royalty is officially uniting on camera. Acting powerhouses Kate Mara and Rooney Mara are set to share the big screen for the very first time in their careers, and they have legendary director Werner Herzog to thank for bringing them together. Even better? The iconic auteur managed to pitch them using the most old-school method imaginable. While chatting about their upcoming movie *Bucking Fastard* at the Toronto International Film Festival, the sisters revealed that Herzog didn't just have an agent shoot over a standard email. Instead, he sent a joint physical letter addressed directly to the siblings. Kate admitted it was a surreal moment to receive handwritten outreach from one of her personal creative idols detailing his visionary new project.

What is Bucking Fastard about?

The storyline for *Bucking Fastard* sounds delightfully unhinged. The Mara sisters play a pair of close-knit siblings who possess an eerie connection—so close, in fact, that they actually speak as one. Things take a dark turn when both sisters fall hopelessly in love with the exact same person, triggering a chaotic downward spiral for everyone involved. Adding even more star power to the call sheet, major actors Orlando Bloom and Domhnall Gleeson are also along for the ride in supporting roles. The movie marks Herzog’s long-awaited return to narrative filmmaking, standing as his first narrative feature project since dropping *Family Romance, LLC* back in 2019.

With a wild premise and a legendary auteur guiding the ship, film fans are already dying to see how the sisters navigate their very first joint cinematic outing.
