7. Bruce Wayne Died In The Explosion - The Dark Knight Rises
The Crazy Theory: The lead up to the release of Christopher Nolans Bat trilogy ender was thick with speculation, the big point being whether Bruce Wayne would make it to the end credits. And after the film came out, that discussion continued. A popular theory put forward was that Bruce Wayne actually died in the atomic explosion, with poor Alfred only imagining his friend survived.
Why It Cant Be True:I've mentioned this theory before and back then looked at the films reliable viewpoint and clear use of reality. However, much of the key argument for this theory hinges on Alfreds speech early on about the cafe and I can appreciate how some people could read into that. But theres some even stronger evidence that disproves this theory. The Dark Knight Rises doesn't have a one note ending. John Blake takes up the bat mantle yes, but theres even more than that; the Wayne pearls go missing and a the bat signal is restored. These are both events that are most elegantly solved by Bruce being alive; any other solution relies too heavily on speculation and unseen events. Add to that Hans Zimmers score roaring up at the reveal moment and Nolan's intention is clear; this depressingly beautiful theory doesn't hold much weight.
