You can’t write off expected future profits. That would essentially make income taxes meaningless. You can use a depreciation schedule for movies that you’ve produced and spread your tax savings out if you want(and you can avoid doing that by cancelling the movie all together and claiming it on your taxes now as a deduction), but that only matters when you’re actually making future money for the movie that you want to reduce your tax burden on. WB is losing a hell of a lot of money in the future to save money right now.
