According to the Internet Movie Database, an additional scene was filmed, but never released theatrically, for a second (or possibly alternate) training sequence on the front lawn of Sam Seed's straw home. Included in the sequence were various Chinese symbols representing each different attack that Sam Seed would call out. Even though the scene was deleted for the theatrical cut, a still image from the scene with Jackie Chan standing with his left leg raised and holding a tea cup and wine vase has been widely used on several VHS and DVD covers around the world. This scene is apparently featured on the Hong Kong Legends DVD release as well as the UK/US documentary Cinema of Vengeance.
Also, as revealed by Ric Myers in the audio commentary to this DVD, the film's opening fight sequence between Hwang Jang-Lee and his unnamed opponent has also been heavily edited by a good few minutes, due to the fact that the source footage for this fight scene as it originally premiered theatrically has long since been lost or destroyed, and so the fight scene as you see it on nearly all versions of this film released since, including our Region 4 DVD, is notably truncated. You can see this by how abruptly the fight ends.
