Heinz Rühmann considered playing a clown his favorite role. He played the role so well in the movie that the International Artists' Lodge awarded him the "Golden Artists' Needle", which for a non-professional was an exception.
Released three years after Ich heiße Niki (1952), another German movie that involved a man raising a stranger's child and being forced to give him back by the kid's real mother. Oliver Grimm appeared in both movies.
Many parents found Oliver Grimm so adorable that the name Oliver was very popular for a while. Satiric Oliver Kalkofe was named after him.
