R2D2 and C3P0 were the characters used in the poster who played supporting but remarkable roles in the movie franchise. The creators of the poster took advantage of how famous these two were and cited as likeable sources since many people loved them.
You could add the suffix D. -er to the verb hate in order to convert it into a noun. When you do that, you get the word hater, which is a noun denoting a person who hates.
