Film poster research

As I'm planning on doing a romantic comedy, I've decided to have a look at how certain films are shown through their posters.

I like the layout of this poster as it shows only half of the characters faces and has limited colour. The doodles and bubbles I also like as it gives the poster personality and curiosity.

I like the rough and decayed look to the poster, as if their love has lasted for generations, but I might not include this idea in my own poster. The layout and the idea is what I like and it's appeal to teenagers.

The tags and little notes dotted around the characters is a sweet way to express the characters thoughts and personality.

I'm really inspired by the idea of the woman being pulled out from the text, as if ripped out of the characters thoughts so not to distract him. I might not put this into my own poster but maybe something similar.
