Stormzy says he's been working on #Merkyfilm "for a long time" and hopes it will be "a platform for bold, authentic and powerful British storytelling".
"I always say: music is my first love, but film is my second.
"It's a natural extension of everything we do at #Merky - telling our stories, shining a light on real voices and creating space for those who deserve to be seen and heard."
Stormzy established #MerkyBooks six years ago with a prize each year aiming to increase access to the publishing industry for a wider range of voices.
In 2022, he added #MerkyFC (Football Careers) to his portfolio, aiming to support people who wanted jobs in the sports industry, with a youth hub in Croydon opening last year as part of it, complete with a full-size football pitch, recording studio and gaming centre.
As well as Big Man, Stormzy also announced other film projects in the pipeline.
These include a drama series, animation project and a mockumentary as well as a biopic that his representatives say "promises to leave a lasting cultural mark".
