If we're getting into Jackie Chan movies, though, one cannot leave out Drunken Master
Drunken Master is pretty good!
Drunken Master II (re-released in slightly edited form as "Legend of the Drunken Master" in the US) is the one that's typically regarded as a bona-fide classic masterpiece.
I wouldn't recommend watching it. It's really missing a lot of the charm of the original.
They're good for kids because they are funny and full of action without being grim or dark. They're easy to follow, even for young kids, because of the lack of shaky cam and fast cuts.
They're good for adults because of all the crazy choreography and stunts.
Police Story is definitely my favorite!
Who Am I, First Strike, Police Stories, Armour of God, Mr. Nice Guy are all great, too.
Another one of his that I really enjoyed was Who Am I, but I haven't seen it in probably a decade.
I also really enjoyed his recent one with Pierce Brosnan— The Foreigner. It has a far more dramatic tone than the others, but it's great.
Not the same kind of movie (and not Jackie Chan), but Kung Fu Hustle is definitely worth a watch if you haven't seen it. I also always thought that Bjarne Stroustrup kind of looks like The Beast in Kung Fu Hustle (it's the hair and glasses).
