"Strange Fruit: A Love Story" — Nina Simone
Yes, there is quite the controversy going on with the real production of this Nina Simone biopic (which stars Zoe Saldana in the titular role). But beyond the light skin vs. dark skin rhetoric; the bad make-up jobs and the overall disdain being directed at "Nina," we have to note that it is not an official, co-signed project by Nina Simone's estate. So, with that in mind, an alternate one starring Adepero Oduye should quickly go into production.
Whether the film focuses on her travels abroad, her issues with racism in America or all of the above — the best thing about biopics is casting — and Adepero would make a fine Nina Simone. If you want to know where most singers got their grit from, then this would be the film to watch to learn.
