At 2'9", Weng Weng is considered to be the shortest man to ever take the lead in a martial arts or action movie.
This was the last Agent 00 film, following Agent 00, and For Your Height Only (both released in 1981). This film's closing credits promised a fourth installment called License Expired, but it was never made.
Weng Weng wears a John Travolta Nur Samstag Nacht (1977)-like white suit throughout the entire picture.
