What's with the jars?

Lisa wears a Siouxsie & The Banshees (band) shirt and has a poster of Siouxsie Sioux (lead singer) in her room.

The end credits music is one of their songs, "The Killing Jar".

That's as much of a connection I could find.

The lyrics also vaguely parallel aspects of the movie.

My verdict is that the movie was inspired by the song.

I thought that the butterflies in the jars were a symbol of innocence. He kept saying that he controlled what happens in his house. So basically, it's innocence trapped.

It seemed to me that each butterfly in a jar represented a girl/family that Edgar had killed.

If you caught in the opening credits, there are the jars on shelves that each hold a butterfly. Like a collection. But you can also see faces, crying out, in those jars. The faces of all the girls Edgar has killed and trapped in the house. Like a collection. The jars are also in the cave filled with items of those he killed. Again, a collection.

This will obviously contain spoilers.

The version I just watched was 1h 37m. I don't know if it is an extended version or if you just missed the scene.

At 1h 21m, they are back in time when the killer is a kid and I believe it shows him killing his parents. He sees Lisa and she runs away and hides in a room. This was the killers room when he was a kid. He has multiple frames on the wall with butterflies pinned up or maybe they are posters. There are shelves lined with jars filled with live butterflies similar to the beginning of the movie. They zoom in 4 or 5 times to give you a closeup of the jars with butterflies.

Here is what the killer says from the subtitles:

Get out of my house, Lisa.

Where do you think you're going, little butterfly?

You cannot hide from me in this house

and certainly not in my own room.

I don't need your company anymore.

I don't need your family's.

I got a new one to add to my collection.


So, the killer started collecting as a kid with butterflies and then moved onto collecting people. If you watch the beginning, the jars have butterflies, but they also contain people faces that are screaming for help. There is one butterfly that is not in a jar. It is flying free past all the other jars as they scream for help. I believe that butterfly is supposed to represent Lisa.
