Irene Wan Bik-ha, formerly known as Wen Biyu, is a Hong Kong actress and singer and producer. Her father was an officer of the Republic of China Army. In her early years until she got married, she was known as a "sexy beauty" and was rated as loving beauty more than acting. However, in the 1990s, her film career sputtered when she agreed to star in All of a Sudden (1996), which would be her first, and only, time appearing full-body nude in movie and the hot scenes lasted more than 4 minutes (compared to Everlasting Love (1984) where she had 5 hot scenes, but she was only half nude, and the scenes were less than 2 minutes. And a lot of the hot scenes of her later films are not as daring as All of a Sudden (1996). This move failed to ignite her career. But she later went on to star in various TVB dramas. In 2019, she was 53 years old, but there was a hot scene with two younger actors (the male actor 14 years younger than her and the female actress 27 years younger than her), causing mixed comments. Especially her gay hot scene with a female actress younger than her made the press talk excitedly. However, her lead role in this film still helped her win the Best Actress in a Leading Role award at the 8th Silk Road International Film Festival 2020.
