I just recommend you to lose your hopes about Victor Erice, he doesn't receive the respect he deserves from producers. 
One example is his film "The South", the last 50 minutes of the film weren't made just because the producer wanted to have it finished to show it in Cannes. In those 50 minutes the girl Estrella would have gone to "the south" to know the other family, and the other life of his dead father (and the great Fernando Fernán-Gómez had already agreed to take part in the film).

Three years ago, Erice was going to make one film called "El Embrujo de Shangai", but the producer obligued him to change the script three or four times, and finally he gave the project to Oscar winner Fernando Trueba.
