Given scene/plot descriptions from movies or TV shows, and given a specific question about the scene, summarize the question into a title

[Q]: I was watching Batman: The Dark Knight the other day and something jogged my memory. There is a scene where the Joker puts two bombs in two separate boats and gives the detonator to the boat owners. He claims that each boat can use the detonator to blow up the other boat, before the other boat does the same. Eventually, the time limit runs out and no boats explode, thus proving that Gotham is good and redeemable. Now, I'm not sure if I imagined/dreamt/read somewhere that each boat had in fact its own detonator. If they pressed the button, they would blow themselves up, not the other boat. This would be an even larger twist on the game. Is this actually real? Is this what happens in the comics or on the original Batman movie? Or did I just read this on some theory on the web?
[A]: What did the Joker's detonators actually target?

[Q]: I've noticed a trend recently where, in a particularly violent scene, blood will end up on the lens of the camera. It's not restricted to blood; it could be water, if it's a particularly stormy scene, or mud in, say, a battle. Any kind of liquid, really. The point is that the scene is usually pretty charged. Has this become fashionable and, if so, why? I don't recall seeing this as much when I was younger -- but maybe I just didn't notice -- and, for me, it breaks the suspension of disbelief. I presume the production team are in control of the filming enough such that they can choose if or when this happens, rather than it being accidental. Is it a meta thing to try to suggest to the viewer that the scene is so chaotic, that even the producers can't control it?
[A]: Blood on the lens

[Q]: According to the TARDIS Data Core there was about two or three years between the appearance of the 9th doctor and his regeneration. From the same source we can estimate that the 10th doctor lived around seven or eight years. However the doctor claimed to have lived in his 11th incarnation for around three hundred years! Why would Matt Smith's incarnation of the doctor live so much longer than his 9th or 10th, given Matt Smith and David Tennant portrayed the character for roughly the same number of episodes?
[A]:
Why did the 11th doctor live so long compared with his predecessors?
