I know as an Aikidoka there is not a whole lot of films with Aikido in it but I love Marked for death, Steven seagal acutally does aikido Technics in this movie!
all of seagal's movies are peppered with aikido techniques. I noticed he prefers lots of sankyo type locks and throws.
My favorite is "Above the Law" because he threw only one punch in the movie. (That's the way I remember it, anyway.) Never seen someone kick so much ** with so few punches, or kicks, or elbows, or something.
