This is an excellent mid 80's Hong Kong action comedy movie, ****1/2 stars excellent, based on being 80's action movies made at the time, with an impressive and cool looking Hwang Jang Lee, and an out of character Wang Yue as the villain after money blanks traitor Hwang jang Lee stole. What keeps this from being a **** 80's Hong Kong action movie is that Hwang Jang Lee's character has little to do with the rest of the characters, as Hwang's scenes are almost cameo scenes, and that the 80's spit microphone punch and kick sound effects aren't used, as the softer Taiwanese sound effects are used, taking the impact away from what could have been a perfect Hong Kong 80's action movie, and Chan Wai Man's cameo is short and disappointing as a bumbling thief who has an unrelated comedic sub plot to the rest of the movie, as Chan doesn't get to fight Hwang. However, Hwang makes this a decent 80's Hong kong action movie when he returns 3/4 into the movie to team up with his sister and the rest of the bumbling characters to tak eon Wang yue and his gang. The final fight is pure Hong Kong kickboxing and brawling at it's best, without the proper sound effects. This movie was directed by famous Shaw character villain, Wang Lung Wei, which Wang is reunited with Hwang Jang Lee and Wang lung Wei from Kid from Kwangtung(1982). Hwang Jang lee was in his prime until the late 90, when he went back to Korea to officially retire and do a few movies there. Innocent interloper is a movie made late in Hwang Jang Lee, and he gets better, powerful, and faster with age. Just take a look and this movie and see.
