Dianne,
Me too I had not heard of it until last month when Hollywood Suite were showing Desperado then Once Upon a Time in Mexico, I was going to watch Desperado for the first time and just out of curiosity I checked out El mariachi then went on IMDB to be sure it was the first of a trilogy. From the comments I have seen you can watch Desperado before but I never do that, movies have to be in order for me. Well, I did made an exception with the Fast And Furious movies, I have yet to see the sequel and I did not made one effort to see it before watching the third then fourth (still have not seen the others
im VERY behind in movies).
