Rafa
Serving the story of an icon
This biographical sports documentary is one for the books. Rafa traces the legendary former Spanish tennis player, Rafael Nadal, and his professional career and journey.

The series captures Nadal navigating injuries, training, and the high demands of elite competition while reflecting on the journey that took him from a young prodigy in Spain to a global icon.
Rafa uses never-before-seen archival footage with his family, coaches, and longtime opponents like Roger Federer, Novak Djokovic, and John McEnroe to paint a portrait of the tennis icon. The documentary is directed by Emmy Award winner and Oscar nominee Zach Heinzerling (Stolen Youth).

The Crash
The fatal fallout and its hidden secrets
Every month, Netflix gives us a neat roster of true crime titles, and this one joins the list. The Crash takes a closer look at the 2022 case of Mackenzie Shirilla, a teenager from Ohio whose high-speed car crash initially seemed like a tragic accident. Her car, traveling 100 miles per hour, had crashed into the side of a brick building, killing two best friends riding inside. But as investigators dug deeper, the case took an unexpected turn, with prosecutors arguing that the collision was intentional and tied to a personal conflict.
The Crash dives into the courtroom battle that sparked intense debate over motive, mental state, and the dynamics of the trio present during the accident: Shirilla; her boyfriend, Dom; and his friend, Davion. It revisits the events leading up to that night, piecing together witness accounts, digital evidence, and trial testimony to examine how the story unfolded in real time.
The Crash begins streaming globally on May 15, 2026.
