An interesting tidbit re: ISTL and when TH came aboard.
I watched a video of MA and Dante Spinotti from the Middleburg FF. MA was talking about when he and TH had dinner and MA offered the role to TH. According to MA, it was at some point after War Horse and he offered it to TH on the spot - explaining that he didn't have a green light with money and he wasn't sure when it would be made, but that it would be made. MA said TH agreed to come aboard at that dinner.
I wonder if TH agreed, on a handshake and without looking at a script, because haunted, tragic genius has often = OSCAR in recent history. And because TH sometimes gets so excited that he puts the cart before the horse.
I think actors sometimes think their talents can overcome a dodgy script even though a script is the foundation of a movie.
