Lam Ching-ying
Golden Harvest attempted to make an English-language version of "Mr. Vampire" under the title "Demon Hunters". The film was produced by David Chan. However, the team could not get Lam Ching-ying to reprise his role because the latter was busy with another film overseas. Yuen Wah, who worked on the original "Mr. Vampire", replaced Lam and handled the action sequences as well. American actor Jack Scalia, who acted in the 1978 television series "Dallas", was also recruited into the cast.
