Sophienlund (1943)

The successful writer Erich Eckberg lives with his wife Sigrid and their three children -- the twins, Knut and Michael and the daughter Gabriel -- on their estate "Sophienlund". On their sons' 21st birthday, Eckberg tells them the great family secret: Knut and Michael aren't his children (happy birthday, kids ... oh! and did I mention Santa Claus doesn't exist either?). But thankfully, the news gets better: their real mother died giving birth to them (guilt trip ... guilt trip!) and the Eckbergs decided to adopt the boys and bring them up in a proper family (no doubt so they could shatter their lives with this tale on their 21st birthday). But hey: it made everyone forget about the War going on outside the theatre, right?

Unfortunately the movie Sophienlund is not yet available on HBO Max.
