When looking for an actor to play Lei, the director had fancyed Jamie Fox from the very beginning. He expressed his biggest concern, that is, no matter who plays Lei, he must show his innate musical spirituality. Hackford did not expect that Fox began to learn piano from the age of three, had led the Texas Gospel Church Band, and won a piano scholarship at the university. Heckford, who learned of Fox's music background, was relieved immediately. Getting the approval of the chief creators is only the first step, and Jamie Fox must also be tested by Ray himself.
Before starring in the film, Jamie Fox's knowledge of Ray was limited to music. In order to interpret the characters vividly, Jamie Fox completely immersed himself in Ray's world. From Lei's hairstyle to habitual movements, he has to imitate one by one. Learn braille at a braille school, cover your eyes for 12 hours every day during the rehearsal period, and thoroughly experience the life of the blind. Fox discovered that some changes followed, his hearing became very sharp, and he could even catch sounds that other people could not hear.
