10 Sci-Fi Movie Endings You Can No Longer See
7. The Autobots & Decepticons Make A Truce - Transformers: Dark Of The Moon
The original ending for Transformers: Dark of the Moon actually remains in the movie's novelisation, where Decepticon leader Megatron (Hugo Weaving) makes a truce with the Autobots and heads back to Cybertron in defeat.
This ending would've brought the Transformers trilogy to a clear conclusion, yet somewhere along the line, the decision was made to reshoot the ending to be more open-ended.
In the final movie, Megatron offers only a hollow truce which Optimus Prime (Peter Cullen) soundly rejects, before decapitating him and executing Sentinel Prime (Leonard Nimoy) for good measure. As for the remaining Decepticons, it's assumed they'll be back for the next movie.
Ever since the film's release, rumours have suggested that Bay changed the ending after the novelisation was leaked online ahead of release, but it's just as likely that Bay simply felt the film needed a punchier, "cooler" ending during post-production.
