Norman Panama’s penultimate directorial effort, Barnaby and Me was originally filmed for Australian television. The title character is a talented Koala Bear, who is to Australian fans what Benji is to Americans. Pausing in his escape from a vengeful mobster, American con artist Caesar falls in love with Juliet Mills, whose daughter Sally Boyden keeps Barnaby as her pet. The kooky koala teans up with Caesar for a series of picaresque adventures.
The siblings Kate and Ben and their friend Spider are fascinated by an old mansion called ‘Castle House’ on the far side of the river next to their village. The mansion has been uninhabited for 15 years, but when they explore the premises they notice a mysterious coming and going. When the old owner, the friendly Mrs. Markham suddenly appears – and as suddenly disappears again – things become even more mysterious.
