Back to the Future 4 picks up several decades after the events of the original trilogy, but this time, Marty McFly (Michael J. Fox) and Doc Brown (Christopher Lloyd) pass the baton to a new generation of time travelers. The trailer opens with a nostalgic flashback to Marty and Doc’s last adventure, showing the DeLorean being retired. However, the peace doesn’t last long.
Tom Holland stars as Marty McFly Jr., the son of Marty and Jennifer, who stumbles upon his father’s old time-travel notes while cleaning the garage. Holland’s character is a bright, curious teenager with a love for adventure, much like his father. One day, he uncovers a hidden message from Doc Brown, warning that time has become unstable once again. Doc has been missing for years, but his message suggests that something went wrong during his travels, and a new, mysterious threat is altering history.
Marty Jr. follows the clues and is led to an underground lab where the DeLorean has been restored to its former glory. With no other option, he hops into the car and sets off to find Doc. The trailer then shifts into high gear as we see Holland traveling to different points in time—both familiar locations like 1955 and new, unexplored eras. He meets younger versions of iconic characters and faces humorous and perilous situations reminiscent of his father’s adventures.
However, the stakes are higher this time. A new antagonist, an ambitious young inventor from the future (played by a yet-to-be-revealed star), is determined to rewrite history to benefit himself, causing catastrophic changes to the timeline. Marty Jr. must work with a younger version of Doc Brown (using cutting-edge de-aging technology) to prevent the villain from erasing key events in the past.
The trailer culminates in a thrilling, high-speed chase through various timelines, as Marty Jr. and Doc race to save the future. The trailer closes with a tease of a shocking twist involving the original Marty McFly, setting up even more adventures to come.
