Mike Tyson -- Kung-Fu Fightin' ... In Brand New Action Flick

Mike Tyson's boxing days are over, but he's proving his fists still have fury ... starring in a new Kung-Fu flick alongside some of the biggest names in martial arts movie history.

The trailer just dropped for "Ip Man 3" ... the follow up to Ip Man 1 and 2 ... and it shows Mike calling punks out to see whose hands are the most lighting fast between a boxer and a Kung-Fu master.

Mike's in some GREAT company ... the movie stars Donnie Yen as Ip Man (The guy that trained Bruce Lee!!) and Sammo Hung, who between them have starred in over 239 movies ... most of which are the flying-kick-to-the-face variety.

Check out the trailer ... you get to see a little vintage Mike workin' the speed bag (he's still got it) but if you wanna see him throw down with the big boys on-screen ... you might need to buy a ticket.

We can't wait.
