Production
Development
The series is a collaborative production between Studio Dragon and Jumbo Film, with MBC overseeing the planning and broadcasting. Director Han Dong-hwa, noted for his work on genre-defining dramas such as Bad Guys 2 (2017–2018) and Shadow Detective series (2022–2023), was appointed to lead the project. The script was written by Jang Won-seob. The production team aimed to blend "realistic action" with "salty comedy", focusing on the domestic and professional struggles of middle-aged protagonists—a demographic often referred to in the Korean title (a wordplay on "50%" and "50s Pros").
Casting
Shin Ha-kyun, Oh Jung-se, and Heo Sung-tae were cast as the central trio in November 2025. In late 2025 to early 2026, additional cast members were announced. Lee Hak-joo joined to provide a younger counterpoint to the veteran leads. Kim Sang-ho was cast following his role in Typhoon Family (2025). Kwon Yul was cast in the antagonist role. Shin Dong-mi was cast as spouse to Shin Ha-kyun's character. And Kim Shin-rok's casting as a police-turned-prosecutor was confirmed.
Release
In December 2025, MBC included Fifties Professional in its 2026 drama programming slate. The series is scheduled to premiere on MBC TV on May 22, 2026, and will air every Friday and Saturday at 21:50 (KST). It will also be available for streaming on Viki and HBO Max in selected regions.
