Delaney Buffett found the inspiration for her Tribeca Film Festival–featured Adult Best Friends in an unlikely place: midway through her toast at the wedding of her childhood best friend, Katie Corwin. Buffett, the daughter of Jimmy Buffett, began to joke about being “replaced” by Corwin’s now husband, before having the split-second realization that it wasn’t a joke at all. Influenced by comedies such as Bridesmaids and Booksmart, Buffett wanted the heart of Adult Best Friends to be the authentic friendship between two women. That’s why she and Corwin decided to not only write the film together but also to play the two main characters. “Since we’ve been friends for 20-plus years,” she says, “that came easy.” Buffett directed the film and assembled a cast of real-life friends, including Cazzie David, Cory Walls, and Zachary Quinto. “We knew everyone in the movie is so funny in their own way, and they have such a specific brand of comedy and a specific voice,” she explains. “So being able to know that, and then reverse-engineer a character from there, was amazing.” —Paulina Prosnitz
