The bird Wally was a cockatoo that often refused to perform when needed and squawked loudly off-camera, frequently causing problems with the sound recording. He eventually escaped from his cage and was never seen again.
In order to film in the lake where Anders was rescued by the two girls, the actors had to have injections as the dirty water was a dumping ground.
The majority of this film was shot with a hand-held camera.
Shot in 10 days.
