Unlike Cucumber, which is a self-contained serial following the story of one gay man, Banana is an anthology series focusing on the wider LGBT spectrum.
[3] Whereas Davies' 1999–2000 series Queer as Folk focused on gay men in the Canal Street club scene, Cucumber is a self-contained serial following the story of one middle-aged gay man, Henry Best (Vincent Franklin), Banana is an anthology series focusing on young characters across the LGBT spectrum.
[3] Davies insisted that a transgender actor be cast as Helen, going so far as to alter the script until Black was cast at the eleventh hour; Black was vocal in her praise for this, contrasting the decision with the casting of Jared Leto as a trans woman in the recent film Dallas Buyers Club, which she described as "a cisgender guy trying to play what he thought a trans woman would be like", and compared cisgender actors playing transgender roles to blackface portrayals in shows such as It Ain't Half Hot Mum.
[3] Helen's episode also features Cucumber character Cleo Wilkinson (Julie Hesmondhalgh), in a scene that symbolises a "passing of the baton" between Hesmondhalgh—the cisgender actress who portrayed the transgender woman Hayley Cropper in Coronation Street between 1998 and 2014—and Black and the wider trans community.
[5] The series premiered on Logo in the United States on 13 April 2015 to a very low 24,000 viewers, which was less than half the viewership that had watched Cucumber before it.
