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

Example Input: 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?
Example Output: What did the Joker's detonators actually target?

Example Input: I don't feel like The Hunger Games: Catching Fire fully explained this. It seems awfully convenient to have a tree where lightning strikes 12 times every hour. What would possibly be the point of this in the "game"? It would only kill someone if they were on it.
Example Output: What was the purpose of the lightning tree?

Example Input: After watching the HBO bio-documentary on Robin Williams titled "Come Inside My Mind", one of the things I was very interested in was that Steven Martin and Robin Williams acted together in Samuel Beckett's classic play "Waiting for Godot". There is some footage of this play shown in the documentary and I found a listing for a DVD in the New York Public Library System. But is this the only copy available?
Example Output:
Was Steve Martin and Robin William's stage performance of Waiting for Godot ever released on film?
