- Inspired Stephen Sondheim to make the musical "A Little Night Music".
- This light, frothy piece (in terms of Ingmar Bergman's general oeuvre) was made whilst the director was undergoing financial troubles, stomach pains (he weighed only 125 pounds at the time) and a romance with Harriet Andersson that was on the rocks. Bergman later said that if he hadn't made this film when he did, he probably would have attempted suicide.
- To add to his woes, Bergman's producer at Svensk Filmindustri informed him that he would not be able to finance his next film if this one didn't perform at the box office.
- Filmed in 55 days in the midst of a heatwave.
- On Time magazine's 100 greatest films list.
