Josh O’Connor is best known to most audiences for his Emmy-winning performance as a young King Charles in seasons three and four of "The Crown." But for his new film, "Challengers," co-starring Zendaya and "West Side Story" star Mike Faist, he’s showing a whole new side of himself. O’Connor plays tennis pro Patrick, one-third of a love triangle with Tashi (Zendaya), a tennis pro poised for greatness before an injury relegates her to coaching, and Art (Faist), another well-to-do tennis pro.Tashi eventually marries Art, and Patrick comes back into their lives years later, kicking off tensions and connections, including a racy threesome.
