who vs. whom
I watched some movies over the weekend, and by doing so some questions arose regarding the use of who and whom.
In the movie “Prometheus” one of the main characters is describing the reason of traveling to a planet so far away from earth, and a suporting character says: “We are here because of a map you two kids found in a cave?” - “Not a map, an invitation” - “From who?”
Now, I think the guy is asking for the object. Is he not? Also, I understand that whom must be used after a preposition. Then shouldn’t it be “from whom”?
In the movie “X-Men: First Class” two CIA agents are conversing and the following dialogue takes place: “A war is about to begin.” - “I know. But a war with who?” Same as the other one: Shouldn’t “whom” be used here? “with” is also a preposition, and he is also asking for the object.
