Kung Fu VS Acrobatic (aka Thunderbolt 1991) is a 1990 Hong Kong martial arts fantasy comedy film directed by Taylor Wong Tai-loi (黃泰來) and starring Andy Lau Tak-wah (刘德华), Natalis Chan Pak Cheung (陳百祥) and Joey Wong Cho-yee (王祖賢). The film is a homage to the 1964 martial arts film Buddha's Palm which starred Walter Cho Tat-wah (曹達華), who also acts in a supporting role in this film.
The film starts as Mo Tak-fai (Andy) and Lai Chi (Natalis) visit Mainland China and discover an ancient cave that houses what is supposed to be the makeshift tomb of the legendary martial artist Lung Kim-fei (Walter). The friends find an old kung fu book and practice some kung fu, which unintentionally breaks open a wall and releases a dormant Princess Wan-lo (Joey) and her Handmaiden Siu-man (楳小惠 Cutie Mui Siu-wai). Tak-fai and Lai Chi take the Princess and her Handmaiden back to Hong Kong with them, unaware that they are followed by the just-awakened evil warlord, Tin-chan (元華 Yuen Wah).
