I discussed this phenomena during my look back at all the films I have seen in the theater. Often times, there are 2 movies being produced concurrently, that deal with the same subject- 2 asteroid movies, 2 volcano movies etc. Some kind redditor made a listing of 29 of these incidences. A couple are spaced apart by a few years (Taken and Stolen for example) and I would consider that a bit of a stretch. The rest are solid though. Enjoy!
