Well if it's hardcore athletism that you're looking for, then Tony Jaa is the person to follow. Ong Bak was a good intro movie, and Warrior King has my favourite fight scene entrance of all. Ong Bak 2 and 3 are impressive, but ultimately they aren't proper films, just a collection of fighting scenes loosely cut together. However these are "serious" martial arts films.

I'll be sure to check them out. I will say I find myself interested in the Shaw Brothers stuff a ton. I kinda like the plot combined with great fighting that is just fighting really. I'm more avoiding the kind of stuff that is more like art instead of kung fu.

I enjoy many of Jimmy Wang-Yu's films - he was the hero in "Master of the Flying Guillotine". That's my favourite of his films, but I also enjoyed "One Armed Boxer" and "Chinese Boxer", and thought "Beach of the War Gods" and "Point the Finger of Death" were decent.

If you enjoy MotFG, you should also check out "Shanghai 13" - while it doesn't have the same ridiculous powers, it does have a similar feeling of non-stop kung-fu with only brief interludes to transition between fight scenes. It also features a lot of zany "styles". I loved it.

If you liked Riki-Oh, be sure to check out Killer's Nocturne by the same director. Sadly, it has more drama and less fights than Riki-Oh, but the fights that are there are still wonderfully violent. Plus, it has a man boxing a kangaroo!

As has been mentioned by others, Shaw Bros have done a lot of great kung fu movies. I particularly like "Five Elements Ninjas" (easily the most violent Shaw Bros film I've seen) and the "Venoms" movies.

Hah, I was going to post Crippled Masters, I cannot believe someone beat me to it! The oddest kung-fu movie I have ever seen.

How about Kung Fu Mahjong? Saw this on Netflix one day and watched all three of them. Barely has any kung fu in it and what it does have is meant for laughs - its really a comedy about mahjong.

Most movies mentioned in this thread are good choices. Several people mentioned The Protector already, which I would also recommend - it was excellent.

I was about to say "Any movie with Bill "Superfoot" Wallace in it is worth watching."...

...but now I am unsure if people are referring to the 1985 Jackie Chan movie, or the 2005 Tony Jaa movie?

Probably the latter then, unfortunately it lacks Bill Wallace. :( But yes it was still great, I just didn't recognize it by the name "The Protector" as I originally saw it in Thailand.

If you're at all interested in wuxia-style stuff, I was really impressed with Duel to the Death

I don't remember a whole lot about Drunken Monkey except that I found it very charming and funny, and you can get is used for $3 + shipping

From there, I'll just second a few other suggestions.

Tony Jaa really is impressive. Check this shit out

Fist of Legend, with Jet Li, really impressed me; a great deal more than anything I've seen with Bruce Lee, honestly. Bruce Lee was an amazing martial artist, but had the problem (in the movies I've seen with him) of always so outstripping his opponents that his fights had the air of martial arts demonstrations, rather than ... fights. But I'm clearly in the minority, there.

I started writing this post thinking I'd be able to give a bunch of suggestions, but I'm helpless; when I get back home I'll glance through my collection and see if I can find some gems that I'm forgetting (I mean, I clearly am, I have a pretty big collection, it's absurd that I can give so few actual suggestions)

Ong Bak is pretty good action wise. Tony Jaa is amazing in that movie.

Karate Tiger / No Retreat No Surrender was really good.

Has anyone seen The man with the iron fists? I'm not sure if I should get it on DVD. The reviews were kinda mixed.

I remember this old one I got on a cheap $1 DVD called Dragon Lee Vs the 5 Brothers that was pretty good. Also, there was one that had a name that I can't remember, It ended with "of Kung-Fu" and had the word "Mantis" somewhere, and it was really trippy. It had a woman that got kidnapped and then turned into a half-mantis half-woman at the end and fought the main character

Who do you think taught them...

Has anyone mentioned "A Fist Full of Yen"? Classic. Timeless. Kung Fu cinema at it's best.

YES!!! Take him to detroit for calling him yellow bat, that should teach him :P

By the way, I don´t know if anyone mentioned it either but ¨Ying Xiong¨ (or ¨The Hero¨) is another superb movie, it´s very, very good. But I guess it´s not for everyone, it takes a lot of traditional and cultural beliefs and turns them into visual showcases, so some people may just see what´s happening but won´t get the meaning behind the happening ; )

Lost count of how many times I've watched that scene:D It is truly awesome!

I haven't read the thread so apologies if it's already been mentioned, but the original Drunken Master with Jackie Chan (not the one released in the past 10 or 15 years, the one I'm talking about was released in the 70's iirc) was phenomenal and showed Jackie at or near his peak.

The english dub is terribad but the kung fu and drunken master style is a sight to behold.
