Twenty-eight-year old Eliza Sam (岑麗香) is one of the most heavily promoted newcomers of TVB. With her sweet and cute outlook, her popularity rose quickly among the audience. Since starring in last year’s Divas in Distress <巴不得媽媽>, Eliza won the netizens’ favor with her goofy girl image. She is said to be surpassing the popularity of Christine Kuo (苟芸慧). Possessing an extremely hardworking personality, Eliza has been filming drama after drama, while also shooting advertisements. Recently, she is filming both Sniper Attack 2013 <神槍狙擊2013> and The Hippocratic Crush 2 <On Call 36小時II> at the same time. Eliza displays her best efforts and tries to earn as much money as possible. Earlier, Eliza filmed an outdoor scene for Sniper Attack 2013, collaborating with Eddie Cheung (張兆輝) and Kate Tsui (徐子珊). She was in a full thick sniper uniform in the burning hot weather. Although streaks of sweat rolled down her face, Eliza uttered no complaint. The group’s popularity attracted a watching crowd in no time. Filming The Hippocratic Crush 2 was much more relaxing and easier for Eliza. While shooting a scene with Him Law (羅仲謙) in Sheung Wan last week, Eliza smiled cheerfully and spoke with reporters. Along with her two dramas, Eliza is also currently filming a sunscreen advertisement. She has become the spokesperson in both Hong Kong and mainland China, earning $700,000 HKD. Eliza is known to possess an advertisement image with her friendliness and warmth. With her per appearance fee rising from $30,000 to $60,000 HKD, Eliza is reportedly earning even more than TVB fadan, Fala Chen’s (陳法拉) rate. With many jobs coming her way, money is not a concern for Eliza as she has already surpassed many TVB actresses’ commercial worth. Creds: Ming Pao
Seeing as the audience likes her largely for her appearance/cuteness, it's a good thing she's earning big bucks... Women age fast. By then hopefully she'll have some sort of breakthrough so that she won't have to depend on her appearance anymore.
I would say her breakthrough was Divas in Distress. After that drama.. her popularity skyrocketed. As an acting breakthrough.. not yet.
