People Soup

People Soup is a 1969 short film written and directed by Alan Arkin, with Adam Arkin and Matthew Arkin. The film was nominated for an Oscar for Best Live Action Short Film.

I think the joke here is meant to come from the slightly sarcastic commentary from the observing adults as the two Arkin children (Matthew & Adam) hum, cycle, sing and play at what looks like baking whilst they discuss "lizard people stuff" and spat with each other over where the apple sauce might be lurking in the kitchen. Then it's outside for some frolicking about on the lawn whilst it all sets in the bowl. At times it's quite an engaging look at two siblings making a mess and playing but after five minutes it all runs out of steam and by the time we put garlic in their cake I had lost interest in the home movie feel of the whole thing. If they were your kids, then maybe - if not, then not really - even with a live chicken!
