13 Minutes brought two thoughts to mind: Sideshow Bob’s question about Nobel prizes for chemistry and Dominic Toretto's saying that winning is winning, regardless of the margin. And, similarly, losing is losing, whether it's by 13 minutes or a much longer time. A poster claimed this movie was “based on the true story of the man minutes away from almost killing Adolf Hitler.” The key word there is "almost"—which really only matters when dealing with horseshoes and hand grenades. The film’s subtitle is “Er hätte die Welt verändert,” meaning “He would have changed the world.” It's a case of what might have been. I don’t get the fascination, either historical or fictional, with attempts on Hitler’s life. It's like Terminator; no matter how many robots Skynet sends back in time, John Connor always survives—and so did Hitler until he took his own life. It would be interesting if they made a movie about a Hitler from another timeline sent to eliminate this reality’s version of him; maybe the only decent Hitler in existence would have the job of wiping out all his evil counterparts, like in that Jet Li film. According to Wikipedia, historians have uncovered “no fewer than 42 [Hitler assassination] plots.” However, they can't accurately determine the total number because there were likely many undocumented attempts. I know Tarantino had Hitler killed, but Inglorious Basterds doesn’t count; not because it's speculative fiction—it isn't really—but because it's just silly. The movie deserves some recognition for picking such an unusual subject; I certainly wasn't familiar with Georg Elser before seeing this, though maybe there’s a reason for that — after all, I don't know every person who nearly reached the summit of Mount Everest. What makes Elser any more significant than those other 41 people who tried to kill Hitler? He doesn't exactly come across well, at least according to what we see in the film: he has a child out of wedlock that he leaves behind; he seduces a married woman and has another illegitimate child (yes, that’s the word); and he killed eight innocent people when his bombing attempt failed. He doesn't seem particularly sorry about any of it. Hitler is portrayed strangely calmly too—even during speeches, which are the only times we see him, he lacks his usual fiery delivery; even more odd considering the film was directed by Oliver Hirschbiegel, whose Der Untergang features Bruno Ganz’s famous, intensely emotional performance.
