Filming

A costume fitting press conference was held on 19 September 2012, and principal photography began in Hong Kong in late September 2012. A camera commencement blessing ceremony was held on 17 October 2012.

Production relocated to Macau on 21 November 2012.^[4] On 19 December 2012, the crew resumed shooting in Hong Kong. The final scenes of the drama were completed on 1 February 2013. Macau's Koi Kei Bakery is a major sponsor for the serial.^[5]

Main cast

• Ruco Chan as Kiu Tin-seng (喬天生; Kiu Tinsang) — also known as Sam.

Independent, clever, and talented, Sam is a distinguished police officer for the Royal Hong Kong Police Force, taking him only five years to get promoted from the sergeant rank to the chief inspector rank. Sam is Chow Yuk-mui's eldest son, sired by Kiu Sum, who is also a Hong Kong police officer. Rejected by his biological father, Sam suffers through a tremendously difficult childhood and is emancipated by his parents at an early age. Sam is regarded as the serial's main tragic hero. Though he is innately a good-hearted person,^[6] his tragic flaws—ambition and greed—eventually leads to his downfall by the end of the story.

Brother's Keeper is Chan's sixth collaboration with producer Wong. His breakout performance in Wong's 2011 TVB legal drama The Other Truth—his third collaboration with Wong—was what led Wong to cast Chan as the lead actor for most of her newer works. Chan expressed that he has high expectations for the serial and compares its time-lapsing scope to the likes of critically successful dramas such as The Greed of Man and Vanity Fair.^[7]

• Linda Chung as Rachel Cheuk (卓靜; Ceok Zing) — Sam's girlfriend.

Rachel is the second daughter of Lau Lai-kuen, who is the second wife of the wealthy Philip Cheuk. Despite her parents' objections, Rachel insists to date Sam. With Sam's help, Rachel eventually fulfills her dream of owning her own fashion boutiques to sell her own brand designs. She was involved in love triangle with Sam and Son for more than 20 years.

Wong had been wanting to work with Chung ever since she started production on her 2012 comedy, No Good Either Way in late 2011. Chung was one of the first cast members of Brother's Keeper that was announced in mid-2012. On her role, Chung said, "The role grew up overseas, so I naturally get to speak English! I grew up in Canada as well... speaking English dialogue is a very comfortable feeling for me."^[8]

• Edwin Siu as Lo Wai-shun (羅威信; Lo Waiseon) — Sam's younger half-brother.

The younger son of Chow Yuk-mui, Shun is sole offspring of Mui's only marriage with Lo Fu-shing. Due to his father's poor business, Shun spends most of his time in the streets of Macau to handle his own peanut brittle vendor business. Resourceful, persistent, and confident, Shun's small mobile food business eventually expands to a large multi-chained bakery shop, the Pasterilia Lo Son Kei. The simple-minded Shun serves as a foil to Sam's guileful character. Shun's story from rags to riches is also inspired by the real-life story of Leong Chan-kuong, the owner of Macau's most famous bakery shop, Koi Kei^[9]

Moses Chan was originally cast for the role of Shun, which was announced simultaneously with Ruco Chan's casting in the late summer of 2012. In August 2012, approximately a month before the serial was to commence shooting in Hong Kong, Chan was reassigned to play opposite Wayne Lai in TVB's legal drama, Will Power.^[10] After Siu replaced Chan, the character of Shun was rewritten to be younger.

• Kristal Tin as Yiu Man-ying (姚文英; Jiu Manjing) — nicknamed Chang-kai Ying (棖雞英; literally "Shrewish Ying"); Son's best friend.

Peevish, boyish, but loyal, Ying is one of Shun's closest childhood friends. Ying falls in love with Shun and is a major supporter in Shun's quest to open up his multi-chain business.

• Louis Yuen as Lung Fei (龍飛; Lung Fei) — nicknamed Young Master Lung (龍少爺); Son and Ying's best friend.

Educated overseas, Lung hails from a wealthy family in Macau, and is the heir of his family business, although he prefers to work as an insurance sales agent. Despite his family business being one of the biggest rivals of Pasterilia Lo Son Kei, Fei and Son are best friends. Fei has an obvious crush on Ying, but he is supportive when Ying begins to date Son.

• Louise Lee as Chow Yuk-mui (周玉梅; jyutping: Zau Jukmui) — Sam and Shun's mother. Mui gave birth to her first-born, Kiu Tin-seng, in Hong Kong during the late 1960s. Kiu Sum, her son's policeman father, refuses to marry Mui after their son's birth, and in a blaze of anger, Mui destroys her son's Hong Kong birth certificate and moves back to her hometown in Foshan, China. There, she meets her husband, Lo Fu-shing, and gives birth to Shing's only son, Lo Wai-shun. In 1980, Mui and her family attempt to sneak across the Hong Kong borders to escape mainland China's tumultuous social unrest, but the family is separated by external forces. Mui, Shing, and Shun land in Macau, while Sam lands in Hong Kong.
