Good to see someone like myself who likes the old school action classics.
From the above I will add
Police Story I & II
Project A I & II
Drunken Fist II
Same reason as kung_fu_king, the movies I listed are Jackie Chan's movies while he was at his prime shape and without Hollywood influences. These movies beat Rush Hour I and II at anytime.
And how can anyone missed this?:
I bring this up because the movie and Tony Jaa himself reminds me Jackie Chan and Jet Li in, again, their prime performance and without Hollywood influences.
BTW, I don't know the availability of these movies at the western world, but if you by any chance come across these in the ol dusty corner of your local video shop, hire a copy and see what I am saying.
