The amazing thing is, not only did he deliver the packages using the thinnest disguise imaginable ...
"So, how about that local sports team that I totally follow? Am I right?"
... but absolutely no one caught on that he was Tom Cruise, even when he sat down and had an entire conversation with a total stranger.
"So what are your favorite Tom Cruise movies? Like, if I held this gun to your head, first three that jump to mind."
And yes, Cruise did actually take it upon himself to learn the other half of being a professional killer, i.e., how to actually kill people. He did extensive training with guns, learning how to shoot quickly and accurately, all with live ammo. He got so good that, on set, he was able to draw his gun and shoot helpless extras down in just under three seconds. Luckily, that time they used blanks, but we guess what we're saying is that if Tom Cruise ever decided on a change of career, "faceless killer" is totally in the cards. Incidentally, that's why we didn't make any Scientology jokes.
