Twins' effect
When Twins started their singing careers, there were very few musical groups in Hong Kong. However, after Twins' success, other music producers realized there was a huge market for group singers. As a result, more singing groups were formed.
Films
Twins started out their career in the film Summer Breeze of Love in 2002. While they started their film careers together, and are known as a musical duo, they seldom if ever sing on screen. In the film Beyond Our Ken released in 2004, Gillian played as Chan Wai Ching, a spurned girlfriend of the eponymous Ken, where she managed to brings both a charming girlishness and an opaque resolve to the character, and handles her despondency with believable vulnerability. Gillian occasionally gives off the same sweet likability that has characterized her earlier performances, but shows far more than that in this particular film.
Charlene has good reputation among HK directors about her attitude, learning and acting skills. Her psychological thriller movie Diary, by the Pang Brothers has earned her the Best Actress award at the 11th Puchon International Fantastic Film Festival (PIFAN Korean Movie Award). In her movie Simply Actors (2007) , a success at the box office, Charlene portrayed a Category III softcore actress, where she proved to the audience once again that she is not just a cute and bubbly young girl. Instead, she has shown herself to have matured into a young lady capable of taking on a variety of roles. She received numerous nominations for her solid acting, duly identified by an abundance of film critics. Only months later, she left the 2007 Golden Bauhinia Film Awards hand in hand with the awards for Best Actress and Favourite Actress for her portrayal of Dani Dan in Simply Actors.
