Never Back Down gets points because it recaptured the feeling of the old 80's MA films. WMA, Princess Bride.
To me Seagal's first movie, "Above the Law" or "Nico," depending on where you live, has the most recognizable aikido. I thought the Bourne films were largely escrima?
I don't know where to stick that MA-wise but it's a pretty awesome movie: [ame="https://www.youtube.com/watch?v=N9K3E-HETo0"]Hard Times Trailer 1975 Movie with Charles Bronson James Coburn - YouTube[/ame]
The Bourne films were choreographed by Jeff Imada, who has an extensive background in both FMA and JKD, courtesy of Guro Dan Inosanto. So you could make the case either way really.
(To someone who doesn't do martial arts) Rocky- boxing Only the strong- jungle karate Borne- karate Anything by Bruce lee- karate Anything by segal- karate It kinda goes in like that.
The Rocky series: Western Boxing Enter the Dragon: Jeet Kun Do (not a style, rather a methodology) Jet Li's Fearless: Mizongyi Kung Fu Choke: Brazilian Jiu-jitsu (it's a documentary about Rickson Gracie)
