The documentary is narrated by actor Geoffrey Holder (Ray the Sun from Bear in the Big Blue House), who has a deep voice with a pleasant tone, somewhat akin to that of James Earl Jones. His thick Trinidad accent, however, can be somewhat hard to understand despite the clear diction. A couple of scientists provide supplementary narration, but it is not sufficiently clear who they are or what their relationship is to the rainforest. The film ends with a fitting musical number, "Mbube (Wimoweh) (The Lion Sleeps Tonight)" by the South African vocal group Ladysmith Black Mambazo. --Kathleen Fennessy
