I feel to merge that movie from 1973 with another movie from 1979, which uses footage of the early movie, was a bad decision,
since it has even another director, crew, (probably company). And no Jackie Chan (who was doubled completly)...!!
Anyhow we have a lot of movies which have not been merged in that way! Anyhow it will be hard to sort the crew credits out now...
BTW: It has even a short sequence which seems to be an outtake from Drunken Master, with Jackie Chan performing one minute.
