According to a survey carried out a long time ago by the TVE program Spanish Version With the votes of its television viewers, Pedro Almodóvar's Todo sobre mi madre would be the best Spanish film of the 90s, followed by Tesis by Alejandro Amenábar and Martín Hache by Adolfo Aristarain.
Below is the list of the 10 best spanish films of the 90s:
1.- All About My Mother (Pedro Almodóvar)
2.- Thesis (Alejandro Amenábar)
3.- Martin Hache (Adolfo Aristarain)
4.- The Lovers of the Polar Circle (Julio Médem)
5.- Alone (Benito Zambrano)
6.- The Good Star (Ricardo Franco)
7.- Open Your Eyes (Alejandro Amenábar)
8.- Neighborhood (Fernando León)
9.- The Day of the Beast (Alex De La Iglesia)
10.- Nobody Will Talk About Us When We Are Dead (Agustín Díaz Yanes)
I agree with practically all of them, although I would remove Nobody will talk about us when we are dead but I don't know which one I would put in their place.
In addition, it should be noted that Pedro Almodóvar and Alejandro Amenábar have two films, each of which, in the list of the best spanish films of the 90s. And, sure, both would also have at least one movie on the list of the best movies of the first decade of 2000 with Volver and Mar Adentro.
