I have a terrific true story, an unknown piece of 19th century history, full of drama and action and great characters. I was advised by someone I trust in the industry to try to make it into a serial TV series - an 8 parter, because "there's more money in TV". So that's what I did, and the story fits.
But the story ends with a major disaster at the end of ep7, and resolution in ep8, and now I'm concerned that studios will expect ideas for seasons 2 -5, and I don't think that is possible - maybe one more season tops, but that's it.
SO - my question is: with a self-contained story like mine, should I reconsider the format, and think again about whether it could be turned into a movie? Or is a single season 8-parter a "fundable" thing?
(I had one major UK production company interested but they seemed put off by the format - too expensive, so there's a bit of evidence that maybe my problem is the format. But then again, The Terror was TV series true history/horror mashup that gained a second season, and we're led to understand season 2 is set in a totally different era and bears no relation to season 1... )
