According to Safdie, the movie nearly concluded with Marty taking his granddaughter to a Tears for Fears concert in the 1980s. The scene would have shown him settled into a comfortable life with a family and a nice home, enjoying the show from great seats. He’d be reflecting on the song ‘Everybody Wants to Rule the World’ and contemplating youth, success, and whether he was truly fulfilling his purpose. Then, suddenly, Mr. Wonderful would attack him. Safdie explained they even started working on prosthetics to age up Timothée Chalamet for this ending, but A24 pushed back, with one executive questioning if it was the right move. Ultimately, it seems like changing the ending was a good decision.
