Star Jeff Speakman signed a multi-picture deal at Paramount. One of the two of the two planned movies was a sequel to this film, and another script Paramount optioned about a cop fighting a terrorist. After the Paramount deal fell through, that script went on to Twentieth Century Fox and became Speed (1994).
A sequel was planned, but a change of regimes at Paramount meant it never came to be.
American Kenpo founder (and Jeff Speakman's instructor) Ed Parker auditioned for the role of Master Lo.
The black belt that Master Lo wears is American Kenpo founder Ed Parker's original first degree black belt.
James Hong played the villain Lo-Pan in the movie Big Trouble in Little China, the character became the inspiration for Shang-Tsung of the Mortal Kombat games. Cary-Hiroyuki Tagawa who also appears in this movie played Shang-Tsung in the 1995 film Mortal Kombat.
