Richard III is one of the best Shakespeare films ever.In nearly every one of those examples, the filmmakers did not use the titles of the plays they based their movies on....I've seen adaptations of Shakespeare that change the setting to, respectively, 1930s England, 1990s Miami, FL and modern day NYC.
I've seen Prospero turned into Helen Mirren, Othello into a basketball player and MacBeth into a mobster.
Why can the bard's settings and characters be changed and not a comic book's?
Richard III: William Shakespeare's classic play is brought into the present with the setting as Great Britain in the 1930s. Civil war has erupted with the House of Lancaster on one side, claiming the right to the British throne and hoping to bring freedom to the country. Opposing is the House of York, commanded by the infamous Richard who rules over a fascist government and hopes to install himself as a dictator monarch.
Romeo + Juliet: Shakespeare's famous play is updated to the hip modern suburb of Verona still retaining its original dialogue. The gun-toting members of the families wage a vicious war on the streets as the star-crossed lovers, their tragic destiny.
the Tempest: In Julie Taymor's version of 'The Tempest,' the main character is now a woman named Prospera.
Romeo + Juliet...not so much.
As for Akira, I tried watching the anime but couldn't get into it, so I'm not sure how much of the plot and characters rely on a Japanese setting. From what I saw, I'd say not much.
