Maggie Poon (Mei Kei Poon), who played "Bean Curd" in the movie 'Spacked Out', had no previous acting experience. Originally, she only accompanied her classmates to audition at Milky Way Image. She did not participate in the audition, but a staff member saw her, took her phone number, and took a few photos for the record. However, director Lawrence Ah-Mon gave up on her in the first round of interviews because he felt she looked too much like a doll and not like an ordinary person, so Maggie was not originally among the main cast. But assistant director Four Tse Liu-Shut met Maggie while filming an advertisement before shooting 'Spacked Out'. She played a rebellious girl very well. Four Tse Liu-Shut showed the advertisement to the director, Lawrence agreed with her performance, and asked Maggie to play the role of "Bean Curd".

After 'Spacked Out', Maggie was invited by director Soi Cheang to play the female lead 'May' in the movie 'Diamond Hill', and then filmed the horror film 'Inner Senses' directed by Chi-Leung Law, where she played Cheung Siu Yu. In the movie, Maggie had several scenes with Leslie Cheung. Her last film was director Wilson Yip Wai-Shun's 'SPL', after which she faded from the screen.
