Dueling Dubs: The first one (circa 1979) called Fei-Hung Freddie Wong, Beggar So was called Sam Seed, and Yan Ti San was called Thunderfoot. The original dub could be heard on older VHS tapes such as the 1982 Rank Film VHS in the UK. In the later UK re-dub done in the '80s used on DVD and Blu-Ray releases, Fei Hung and his father are still Freddie and Robert Wong. Beggar So is now called So Hei. Yan is called Thunderlegs. The original HK dub was a product of its time with usual cartoony voice acting, awkward dialogue, and unnatural inflections, much like all the Kung Fu dubs of the time with the unintentional hilarity. The DVD dub had both voice acting and dialogue which tended to be stilted or subdued at times in order to avoid the signature quirks of older kung fu movie dubs. Most of the humor remains in what is being said as opposed to how funny it sounds to the ear. Also, much of the translation in the DVD release is more literal. So-Hei has a voice that is curiously similar to Sam Seed's. Interestingly enough, Yan's original English dub sported an accent reminiscent of characters in Spaghetti Westerns. His voice in the later dub gave him a lower, more subdued, deadly sounding voice. Mr. Lee and Gorilla both had cartoony voices (similar to Piglet from Winnie the Pooh) in the original dub but were given more appropriately deeper voices in the DVD dub. However, Freddie's voice actor Daniel Flynn was definitely hamming it up in the new dub.
On-Set Injury: Jackie Chan nearly lost an eye when Jang Lee Hwang (Jim Ti-Sam) kicked him in the head during the final fight scene. When Hwang became aware of this, he refused to do more takes for the shot.
Stunt Double: For many of the more athletic sequences, the 66-year-old Siu-Tin Yuen was doubled by his sons, Cheung-Yan Yuen and Yuen Woo-Ping.
