Zootopia at Wooroloo Primary School will show on April 1 due to forecast rain this weekend.
To avoid a repeat cancellation, the movie night will be inside the school’s undercover area rather than outdoors.
Families are encouraged to bring low-backed chairs and blankets.
The Wooroloo screening will mark the final event in the Shire of Mundaring’s popular Cinema Under the Starlight program.
Doors open at 6pm, with pre-screening activities on offer including face painting and a sausage sizzle.
Proceeds from the sausage sizzle will support the Wooroloo Primary School Parents and Citizens Association.
