Time Out says
As their popularity snowballed from the early days of television broadcast, the iconic Hui Brothers team left behind a trail of vernacular comedy movies that struck a resounding chord with working class audiences. Easily one of the best from writer-director Michael, The Private Eyes immediately impresses with its wordless opening credit sequence showing only the characters’ feet – in which a private detective tails his subject in a pair of miserably broken shoes, only to have one of his soles accidentally ripped off before stepping on a beggar’s bowl and a cigarette stub with his exposed foot. A cheeky, stingy boss who’s all too ready to exploit his employees, Michael’s small-time private eye is nonetheless faithfully aided by a honest, kung fu-fighting apprentice (Sam) and a stupid, stammering assistant (Ricky) who will literally test a bomb for him. Together with the funky soundtrack by Sam and his band, The Lotus, the movie also tapped into our collective consciousness with a range of riotous gags, from aerobics for chicken to a Sammo Hung-choreographed, Bruce Lee-inspired fight scene with flour and sausages.
