His career was cut short when he died in a car crash at 32. However, his legacy has lived on over the last 40 years.
"Ever since seeing Bruce McLaren and Jack Brabham race each other in the Tasman series years ago I've been a McLaren fan. Few people know just how extraordinary his journey has and how much he accomplished in his short life," Donaldson said in a statement.
Matthew Metcalfe, who previously worked on the Sir Edmund Hillary documentary Beyond the Edge, was one of the producer's on the documentary.
"The pride we felt working on Beyond the Edge is a very similar spirit to which we have approached this film. They were both New Zealanders we could all relate to, doing extraordinary things which made history and left a proud legacy for all Kiwis," Metcalfe said.
McLaren will race into New Zealand cinemas in June.
