If your knowledge of Avengers movies begins and ends with the exploits of Captain America and company, you really should check out The Masked Avengers: they haven't got 'superpowers' as such, but their moves are just as awesome, and all executed without the aid of millions of dollars of CGI.
The film follows a group of highly trained martial artists dedicated to hunting down a gang of vicious masked killers for hire whose weapon of choice is the trident. After tracking the masked assassins to the town of Jingyang, the brave fighters find themselves attacked and killed one-by-one. Will they uncover the identities of the gang's three leaders (whose golden masks come with fancy coloured beards) and make them pay before it is too late? Of course they will
To be honest, there are just a few too many very similar characters to keep track of to make this a wholly satisfying martial arts classic, but with so much impressive kung fu, and lots of bright red blood (gory impalements and slashing aplenty), the film still qualifies as an essential slice of Shaw Brothers chop-socky madness.
After much mystery and murderous martial arts mayhem, the whole thing boils down to an absolutely stunning showdown between the baddies and the surviving good guys (who get a little help from an ex-leader of the gang turned hero, played by Philip Kwok), the fantastic finale taking place at the villains' booby trapped temple, which comes equipped with acid jets, arrow traps, and deadly spiked doors.
