A January 1961 Twilight Zone episode called “Back There” and Stephen King‘s “11.22.63” asked the same question: if a person could go back in time, could he/she prevent a tragedy from happening or is history immutable no matter what? This is the dream of Matthew Kiernan. What films or franchise would HE readers try to prevent or erase if they could go back in time? Which actor’s or actress’s career would they like to smother in its infancy? I for one would try and stop the making of the Wachowski brothersSpeed Racer and the Keanu Reeves remake of The Day The Earth Stood Still,
