1970s

In 1970, Wu became a director in his own right. His directorial debut, Wrath of the Sword, was released the same year. In 1971, Wu released one of his seminal works, The Deaf and Mute Heroine. He concentrated on directing in the 1970s, directing several movies – such as Young Tiger (1973) and Wits to Wits (1974). Wits to Wits has been noted as one of the precursors of the knockabout comedy kung fu genre that was later made famous by Sammo Hung and Jackie Chan. Another movie Wu directed, Manchu Boxer (1974), featured Sammo Hung, then a young choreographer and later one of the trend-setters of Hong Kong cinema. This marked the beginning of a strong working relationship between the two, which would become prominent towards the 1980s. He co-directed with his former mentor Chang in several movies – The Water Margin (1972), The Pirate (1973), All Men Are Brothers (1975) and The Naval Commandos (1976).

While most of his output during this period was as a director, Wu continued to appear as an actor and appeared both in his own movies and in several others, although his roles were generally limited to small appearances. During the mid-1970s, Wu joined a small exodus who were leaving Shaw Brothers due to corruption within the studio and became an independent director. Despite becoming an independent director, Wu was still able to work closely with some Shaw Brothers stars such as Ti Lung (The Massive (1978)). ^{[citation needed]}

1980s

As the 1970s and the era of the martial arts film mania slowed down albeit very slightly, Wu Ma's output as a director also slowed. His acting output, however, increased as he became increasingly well known as a popular character actor. Wu had made appearances in Sammo Hung's 1970s movies (such as The Iron-Fisted Monk), his association with Hung began in earnest in the early 1980s. Wu appeared in Encounters of the Spooky Kind (1980). Throughout the 1980s, Wu and Hung had a close working relationship, often with Wu as the director and Hung as the producer (such as My Cousin The Ghost (1986)). Wu worked in Hung's production company Bo Ho as the production manager, and made appearances in Hung-directed films during the 1980s, including Millionaire's Express (1986) and Wheels on Meals (1984).

Towards the mid-1980s, Wu became one of the most prolific character actors in Hong Kong, his now-rubbery face able to shift effortlessly across a spectrum of emotions. During the 1980s, he received three Hong Kong Film Award nominations for Best Supporting Actor – for Righting Wrongs (1986), where he played a policeman having to deal with his son's death; the classic A Chinese Ghost Story (1987) as Yin Chek-Ha, which is considered one of the greatest films ever made; and in The Last Eunuch in China (1988), as Lord Ting. He began a working relationship with Tsui Hark, and appeared in several of Hark's movies. Aside from A Chinese Ghost Story, Wu also appeared in the earlier classic Peking Opera Blues (1986). ^{[citation needed]}

After A Chinese Ghost Story, said by Wu to be among his most favorite movies, Wu began to focus on the supernatural genre. Much of his directorial efforts after 1987 were within that genre, such as Picture of a Nymph look alike mini sequel from Chinese Ghost Story directed by Eric Tsang (1988), Burning Sensation (1989) and Fox Legend (1991). He also co-directed Just Heroes (1989) with John Woo.

1990s

Wu continued his working relationship with Hark, and appeared in Once Upon A Time in China (1991) and The Swordsman (1991). The early 1990s were an especially prolific period in Wu's career – with Wu appearing in over 14 movies during one year. As the Hong Kong film industry began to slump, Wu's career also slowed considerably. After appearing in High Risk (1995), many of his appearances were either in low-budget movies or in television series. ^{[citation needed]}
