The Prestige -2006
Not Batman Begins (5th), Not The Dark Knight Rises(6). Not Inception (4th). Not Insomnia (7th). Not Memento (3rd). I didn't rank Interstellar because I haven't watched it yet. The Prestige is about two friends / partners who from tragedy, turn into great magicians and bitter rivals. This is easily the second best Christopher Nolan Joint. If you have never seen it, please Netflix or Amazon stream this movie. Without giving it away, the ending is so good that you want to watch it again and again. Yes, its full of bad tooth'd Brits and David Bowie as Nikola Tesla. Yes Michael Caine continues his Cal Ripken streak of consecutive movie appearances. The female lead, Scarlett Johansson, graces the viewer just enough.
Inception would rate higher, but it got too much hype.
