Along with Dragon Fist (1979), this movie was filmed in early 1978. As Wei Lo's studio went bankrupt, they shelved both movies due to cost-cutting measures and Chan was loaned out to Seasonal Films for a two-picture deal. While there, he made Snake in the Eagle's Shadow (1978) and Drunken Master (1978) with Woo-Ping Yuen. The success of these two movies at the domestic box-office prompted Lo to give belated releases to this movie and Dragon Fist (1979).
