Heh.
I can't say what was the first film I
ever saw. I do have some memories of my early years before leaving Argentina when my grandmother used to take me to see old Disney films in the Los Angeles cinema (that was it's name), in the center of Buenos Aires. It had a Carrousell indoors and paintings on the walls, and although it was one floor above ground for some reason I always thought it was on the top of some skyscraper. It closed recently.
I saw there a lot of classic Disney films, and also some new films. For some reason I still remember the first film we ever rented, on VHS (Jim Carrey's
'The Mask'), and I remember we rented
'The Little Rascals' about thirty times. My favourite film as a child was
'Space Jam', a favorite of so many kids of my generation*

. The film that completely blew my mind as a kid was when my mom left me alone in the cinema at the age of seven to go see some stuff, I watched 'Fantasia 2000' by myself.
*Speaking of 'Space Jam', recently together with a group of friends, given the assignment of analyzing any piece of art given the subjects we studied along the year, we managed to convinced our professor that 'Space Jam' made reference to the Dada and Surrealist movment as well as the theories of Foucault, Freud, Marx and Zygmunt Bauman. When we were criticized that we were mocking the assignment, our defense was that the mockery was in it's essence a manifestation of our acknowledgment of the subjects given that we were liberating ourself from the panoptic eye of Foucault by defying authority as well as manifesting our imagination in the most Breton-esque of ways. And once again, 'Space Jam' proved the world that anything is possible, if you just spread your wings and believe you can fly.
