Supacell is a 2024 British superhero television series, created and written by Rapman for Netflix. It was directed by Rapman and Sebastian Thiel, and features an ensemble cast, including Tosin Cole, Nadine Mills, Eric Kofi-Abrefa, Calvin Demba, Josh Tedeku and Adelayo Adedayo. Set in modern-day South London, the series is about a group of five ordinary Black British people, unified by family history of sickle cell disease. The sickle cell issues manifests as a super cell (supacell) in their bodies when they unexpectedly develop superpowers, though this leads to them being pursued by a secret organisation who intends to control them.

The series was a difficult sell to US broadcasters, and was rejected by HBO, ABC, and FX. Netflix picked it up in late 2019, ahead of the release of Rapman's feature-length film debut Blue Story. The development and writing process took place during the COVID-19 pandemic in 2020 and filming took place between July 2022 and April 2023 in the South London boroughs of Southwark, Lewisham and Greenwich. The series explores themes such as knife crime, racial profiling, poverty, and the exploitation of black bodies.

Supacell premiered on 27 June 2024 and received positive reviews from critics. In August 2024, the series was renewed for a second season.

Five black people from South London (a delivery driver, a gang leader, a nurse, a financially-struggling father, and a Cockney drug dealer) are unified by a family history of sickle cell disease and unexpectedly develop superpowers. They discover each other and fend off entrapment by a secret organisation seeking to control them.

Rapman's plans to write a superhero series were first publicised in November 2019, during the promotion of his first feature-length film Blue Story. When asked by actor Junior Afolabi Salokun, who appeared in both Blue Story and Supacell, about what he would like to write next, Rapman responded with "I want to do a sci-fi one day. I could do something like a Misfits but a bit deeper. Like imagine someone from where we came from [South London] gets powers? Like real powers, like what would man really do with that power?"

The series was a difficult sell to US broadcasters, such as HBO, ABC, and FX, who all rejected it. During a dinner with some UK Netflix executives where Rapman pitched ideas for several shows, such as an untitled football-centric series, Supacell was successfully commissioned. He began writing the series during the COVID-19 pandemic, following the cancellation of his planned second film American Son, a remake of the 2009 French film A Prophet, starring Russell Crowe and Stephan James, for Paramount Pictures, as a result of the pandemic, and in November 2021, the series was announced in November 2021 with Mouktar Mohammed and Henrietta Lee of New Wave as executive producer and associate producer, respectively. Also executive producing are Anna Ferguson and Steve Searle of Netflix with Mark Hedges as series producer. In August 2024, Netflix renewed the series for a second season.

In August 2022, Tosin Cole was announced in the lead role along with a cast that included Adelayo Adedayo, Nadine Mills, Eric Kofi-Abrefa, Calvin Demba, Josh Tedeku, Rayxia Ojo and Giacomo Mancini. It was later revealed that Eddie Marsan had joined the cast as Ray.

Filming took place between 4 July and 10 December 2022 in South and South East London. Filming locations included Thamesmead, Peckham, Bermondsey and Deptford. It was reported that the production was using a specialised Arri 35 camera which has been designed to show Black skin in the best and most complimentary way. Filming had wrapped by April 2023.
