Many fans have wondered the ultimate DC question. Will The CW's Arrow and Flash be connected to the events of Man of Steel and eventually Batman vs Superman? Now there is both great and terrible reasons why these should or should not be connected. Timeline issues, CW actors on film, continuity ect ect.
Well with all that put aside here is what I believe is a correct representation of the timeline of events that could take place IF DC ever decided to connect CW's The Flash/Arrow to Man of Steel/Batman vs Superman....even through in FOX's upcoming Gotham prequel into the mix as well. (Gotham will not be connected to any other show/movie but was added just because)
This is all based on the current Arrow timeline starting in 2012. Arrow will be working in real time to our timeline with the other events built around it. This is also based on the little information we have on Batman vs Superman. With Batman being an old withered crime fighter long before Superman ect etc.
:: Update :: - Added Green Lantern (2011) to the timeline
:: Update #2 :: - Added NBC's Constantine to the timeline
Some images used are from multiple live-action interpretations of these DC characters.
