Early Gordon Liu appearance - question

[STSH]

I've just been astonished to spot Gordon in a very small part, which was certainly made before he became famous. What I'm looking for it<br>- year of production of the movie, and<br>- any other film appearances he made before becoming famous.<br><br>I'll start with the known facts, then onto supposition and even speculation.<br><br>English title - The Monk<br><br>Translation of Chinese Title - Sex Desire Priest (much more likely to grab you, but thoroughly misleading)<br><br>Written, directed and featuring (small role) - Dean Shek<br><br>Star - Yam Sai Goon (Jen Shi Kwan)<br><br>Support cast includes - Fung Hak On (Feng Ko An, a veteran villain who was apparently nicknamed "The Rapist") and Eddy Ko Hung.<br><br>Action directors - The Liu Brothers<br><br>Plot - a monk is expelled from a monastery when the period equivalent of Playboy is found in his bed. His kung fu skills get him a job with a loanshark, but he eventually returns to the monastery, where his old friend fights him for no apparent reason.<br><br>Gordon appears briefly in a scene where Fung Hak On is foregrounded. He has a full head of hair (!). This is by no means a proper cameo. Gordon floats around as one of Fung's thugs, does not speak, and is very much part of the background.<br><br>The thing which amazed me was all the familiar faces who look so youthful. Eddy Ko looks like he's just out of his teens.<br><br>hkmdb lists Gordon Liu's first film to be made in 1974. Another internet source (can't recall which) says this was his first prominent role.<br><br>Putting all this together, I would assume "The Monk" was made in 1973 or even earlier. However, someone from Mobius thinks it more likely a late-70s el-cheapo production made in between major Shaw Bros flicks.<br><br>Any hard info or informed speculation ?<br><br>
