The Ms. Jackson singer plays the late guitar great in the mid-1960s and was determined to look the part, according to producer Danny Bramson.
He tells Billboard magazine, "The idea of anyone playing Hendrix, let alone a right-handed guitarist, was one of the greatest challenges of the project. I found a really patient teacher and put together a regimen for Andre when he came out to Los Angeles. He sat in a small studio, six hours a day.
"His guitarmanship (sic) had to carry the idea of grace and fluidity... He kept working in a rehearsal room throughout the production."
The film will feature a soundtrack of Hendrix covers, performed by Andre 3000, aka Andre Benjamin. The late rocker's estate refused to let the producers use original recordings.
