When Hooper visits Brody's home, he brings two bottles of wine. Brody pours himself a large measure, and then gives his wife and Hooper some. If you look at the bottle, firstly it seems rather full for the amount he's just poured, and secondly the level changes from shot to shot. Sometimes it's above the label, sometimes below.
The purpose of an Essay Introduction is to introduce the reader to the subject matter you are writing about and to state the intent of the paper.
It would then not be an introduction at all! An essay introduction does not need to do more than tell the reader the topic of the essay, describe how the body of the essay is organized, and explain the thesis that you argue for in the essay.
