Impact on the Future of the Saga
The Last Knight was designed to radically expand the cinematic universe into a shared continuity similar to other blockbuster franchises. Paramount Pictures assembled a writers' room to map out prequels, sequels, and spin-offs.
However, underperformance at the global box office caused studio executives to pivot. Instead of pressing forward with direct sequels to this specific storyline, Paramount shifted focus toward soft reboots and period-piece prequels, starting with Bumblebee in 2018 and Transformers: Rise of the Beasts in 2023.
