The previous commenter was probably mistaking this for Drunken Master, which Jackie starred in along with Simon Yuen, who plays the same character here. Drunk Mantis was director/choreographer Yuen Wo-ping's attempt to make drunken lightning strike twice, replacing Jackie, who had gone on to more personal things, with charisma-challenged family member Yuen Shun-yee (a.k.a. Sunny Yuen), who, although talented, is no Jackie.
The film is further hampered by a less inventive plot, which calls on the villains to simply disappear through most of the second half because they'd just get in the way of the training sequences. Finally, the revelation of the drunken master's family and surprisingly well- appointed home comes as something of a shock, considering the persona created in Snake in the Eagle's Shadow and Drunken Master.
Even so, from a kung-fu standpoint, the film is wondrous. The villains are superkicker Hwang Jang-lee and future choreography king Corey Yuan Kwai. Linda Lin Ying plays Simon Yuen's wife, who is as adept a fighter as her husband, while Yam Sai-kun makes a memorable impression as the drunken master's brother, who specializes in sick-fu (making me wish the film was titled something like Diseased Snake in the Mantis' Claw)! Yam, by the way, would grow up to become the memorable villain of The Heroic Trio and Iron Monkey.
Despite its drawbacks, this is still an exceptional old-school kung-fu movie.
