The story is after the religious mother of 7 kids died, the kids bury her body in the garden and feigned to their neighbours that their mother is still alive. They start to live by themselves until their estranged father comes back. The kids slowly open up to their father but when their trust was betrayed, the uninviting truth is exposed.
The film was directed by Jack Clayton of "Great Gatsby" fame, with music by Georges Delerue who famously provided music for Nouvelle Vague geniuses. The legendary Dirk Bogarde starred in the film, and I also spotted Mark Lester playing the one of 7 kids. Mark Lester famously played "Oliver Twist". It's not the oddest of Bogarde's films who made some pretty underground films such as "Modesty Blaise" and "Despair", but I was certainly not ready to see him as Charlie, a bald headed shabby man!, though I must say he played him brilliantly.
I recommend you to watch "Our Mother's House" if you have a chance, though it has been discontinued unfortunately. I hope it will be reissued one day.
