So a few days ago I asked this question regarding the ending differences of the Watchmen book and movie and it was marked as duplicate to a question from 2011 (answered 2011).
First off, I'm not disagreeing with the duplicate tag.
So, I had a question about the ending, one that I hoped could be solved by a quote from a cast member or crew member. In the original question, one of the answers stated that there was no such quote to be found (2011). Now, my question (and then later added to the original) had an answer that DID have such a quote. Funny enough, the quote was from 2009, but this bears little importance. What is important is that it was believed there was no information, and I believed there could be some given the 4 year gap.
So, how do I ask a question in hopes of finding new information that was not available in an old answer?
Can I do that? Should I comment on an old question? Do I ask anyway, knowing it will get marked duplicate so as to point at the original and get new answers?
