Money down the drain...
It seems that sometimes not even a big budget, well-known cast, and talented production team are enough to save a project from the cutting room floor.
Take, for example, the upcoming Batgirl blockbuster that was shockingly cancelled this August despite a budget estimated to be between $70 million (£57.6m) and $100 million (£82.3m).
Batgirl isn't the only movie that'll likely never see the light of day. From an axed Game of Thrones prequel to a budding blockbuster that was tipped to be the next Avatar, read on to discover why these expensive Hollywood projects flopped before they even hit our screens. All dollar amounts in US dollars.
