When asked about the significance of the title to the film, Mumenthaler explains that an idea can be very subjective. This is what she wants to get across throughout the film. Inés is telling the story of her memories and point of view of the lake and how it connects her to her father.
Mumenthaler includes that nature is very powerful, a reason why the lake is so important within the story.
The Idea of a Lake shares how powerful memories can be when it comes to a person, a family, or a country. Memories are something everyone has and some experience in a collective way.
Although I’m not from Argentina and did not experience life in a dictatorship, I’m able to empathize with the main character through memories.
So with this film, I continue to remember my days at a lake.
Wind in my hair, sun in my face, with my family surrounding me.
