A an aviation and WWII buff I had to choose GREMLINS all WWII pilots had Gremlin sabotaging airplane stories.
A Gremlin is a fantastic creature commonly depicted as mischievous and mechanically oriented, with a specific interest in aircraft. Gremlins' mischievous natures are similar to those of English folkloricimps, while their inclination to damage or dismantle machinery is more modern.
I had to choose The Exorcist for E but Steven Spielberg's Empire of the Sun and E.T. could have also easily been the movies for the letter E. His movies have had a very strong impact on me, A could have easily been A.I. the Artificial Intelligence film... Maybe Spielberg should be my theme next year!
