Ben Drew's directorial debut follows the lives of six people in London, with the stories linked together by new tracks from the UK music star.
Riz Ahmed, who plays drug dealer Aaron, is front and centre on the artwork, which carries the tagline: "We are all products of our environment... Some environments are just harder to survive in."
The poster arrives on the back of iLL Manors's debut trailer. The video teaser introduced Ahmed's character, alongside Natalie Press's Katya, Keef Coggins's Kirby and Lee Allen's Chris.
Drew told Digital Spy last year that he struggled to get the film financed through the BBC because the script "had c**t written on every other page".
iLL Manors opens in UK cinemas on June 6, while an accompanying soundtrack album will be released on June 25.
