I don't know who was the Borean that said that he would be mad if Donnie Yen was just there to wave a stick for two scenes. That would indeed be a pity but that's already what happened in
Blade 2 (and
Highlander Endgame, god I forgot about that

) so I prefer to expect a repeat of that, unfortunately.
I dunno who Donnie Yen is ?
Famous HK martial arts film star, seen in the Ip Man franchise, arguably the biggest one in the current industry after many years of having to take a seat to Jackie Chan & Jet Li (He started in film in the mid-80). He's not as charismatic as they are and I'm not up to date to with his recent career (I found
Sha Po Lang and
Flashpoint to be terribly shit and pretty light on the action, so I'm not going to suffer through any Wilson Yip movie ever again) but there's a number of great classics from the 80-90 with great scenes even though he was rarely the main man.
If you like HK flicks I would recommend
Iron Monkey and also
Dragon Inn (the 92 version) or
Once upon a time in China 2 (he's the antagonist in the last two) for the ones in costumes. Yen was also the star of
Tiger Cage 1 & 2 and
In the line of duty 4 which are competent, action packed, 80's HK crime movies (fairly jank & low brow).
