Filmographies are made up of both the films one makes and those that, for whatever reason, one will never be able to make: they are too expensive or rare, they are illegal, technically or materially impossible, someone else has come up with a similar idea, we have become discouraged or older, they have been erased or lost, etc. In this session we will tell -and partially recreate with infracinematographic resources- some of these unrealizable films.
