Experimental cinema

I've seen a number of experimental films one that comes to mind immediate is "The Umbrella of Cherbourg"  It is a 1964 French musical and the unique and experimental part about it is that all the words in the film are sung. It's unique in it's musical style in which there are is no spoken dialogue at all,but just singing.

I've also watched Pink Floyd's The Wall which is called by Ebert "an experimental indie." It's a rock film with no actual concert scenes. It's an interesting blind of live-action and animation. It's a story told by both the audio and the visual elements on screen.

This next one isn't experimental by some accounts,but many consider it to be due to it basically being a drug fueled trip with out the drugs. Which is Fear and Loathing in Las Vegas.  It has some elements of it, but it's certainty up for debate.

So with these films and many more I haven't had a struggle watching the films thus far. I've seen a bunch of films experiential and not. I've gone to a film festival or two and have watched a lot of the different blocks  including experimental and international ones.
