I've been a big Van Damme movies fan all my life.
My favorite movies of his are:
Any time any of these are on TV, I tend to drop what I'm doing and watch them.
Also now that a couple of decades have passed and things are put in to perspective, I can safely say that Van Dammes acting really isn't as bad as everyone kept saying back in the day. I mean he is a lot more charismatic and convincing in delivering ass kicking lines than most actors doing action movies these days.
While its a shame that he never recovered in Holywood since late 90s, he did have some very good straight to DVD movies.
JCVD, In Hell, Until Death, Wake of Death and even Universal Soldier Regeneration were quite good for straight to DVD.
