Curiosidades

Two of the main child characters were Australian: Dana Wilson (as Barbie) and Colin Peterson (as Georgie). Both children have very noticeable accents. Colin Peterson's accent is particularly strong but it's explained away by the fact his mother, an actress, had spent time working in Australia. However, Dana Wilson's character was supposedly from the Kings Cross area of London and she was a sister of two boys who, in fact, have London accents.

When the children were camping in the woods at night, the two young Australian actors were startled by a bird. Ridiculously out of context, the call was that of a kookaburra--a bird native to Australia and New Guinea. Among the native bird population of the U.K., nothing sounds remotely like a kookaburra. It's not unusual to hear birds and other wildlife not native to the supposed setting of movies, but it's typically a swap of one wild environment sound for another in the hopes film goers won't be savvy enough to realize the respective distinctions.

The song "Gotta' Have Rain" made a brief appearance in the British record charts and was also a big USA hit for Eydie Gormé.

Kathleen Harrison was 66 years old when the film was made. Her son, played well by Sean Barrett, was supposedly about 15 years old (i.e., the age at the time at which children could leave school on their own volition). On the subject, the age for leaving school did not rise to 16 until 1972 and, thereafter, was incrementally raised to age 18 by the year 2015). Sean Barrett appears older than 15 because he was 19 at the time.

Two of the child actors in this movie went on to become successful rock drummers. Mitch Mitchell, who has a minor non-credited role, was the drummer in the Jimi Hendrix Experience; and Colin Petersen (Georgie) was the drummer for the Bee Gees from 1967 through 1969.
