Office is a 2015 Hong Kong-Chinese musical comedy-drama film produced and directed by Johnnie To and starring Chow Yun-fat, Sylvia Chang, Eason Chan and Tang Wei.

Chairman Ho Chung-ping (Chow Yun-fat) has promised CEO Winnie Cheung (Sylvia Chang), who has been his mistress for more than twenty years, that she will become a major shareholder of the company.

Within the neoliberal market, the logic of intrigue rules, complicated by entanglements of love-hate relationships, which weaves a power play and a pathos-laden tragedy inside the office.

[8] Tom Huddleston of Time Out gave the film a score of 5 out of 5 stars praising its stylish dance and song sequences, catchy lyrics and its screenplay by Sylvia Chang as a keenly observed, spiky treatise on office politics.

[10] Clarence Tsui of The Hollywood Reporter praises the film's lavish decorations and technical accomplishments, but criticizes its simplistic screenplay and being unfocused, with little development of the relationships between the characters.
