This is the first Congolo-Americain effort. Three American actors were flown to the DR-Congo. One, Brandon Ray Olive, noticed that a child was limping. He then saw that the child's toe was missing. The foot had apparently been injured recently. Mr. Olive had a first aid kit and dressed the child's wound.
When a policeman tried to take actor Brandon Olive to jail, another cast member (Charles) stepped up and said he should be taken instead. Charles was indeed jailed for a few hours.
Moyindo Mpongo, the lead actor, is actually completely fluent in English and was a rap artist in Korea for several years. He based his accent on what he heard in "Black Panther."
The song, "Buatu, Pingana Kunji," is based on an old Congolese lullaby. The text was translated by the director into Tshiluba, one of the official languages of the DRC, then set to original music. The singer is pleading to the boat that took her son to bring him back someday. The instruments are plucked cello, kora and guitar.
