I was reading an interview with Martin Scorsese in the Times and he said the following:
But, no matter whom you make your movie with, the fact is that the screens in most multiplexes are crowded with franchise pictures.
Is this proper usage? I have always heard you use "whom" when "who" would be the object of the sentence, or more colloquially when it would make sense to say "him/her" instead of "he/she". In this example, if we replace "whom" with "him" the word order doesn't make sense, so I can't figure it out. I think the larger problem is he ended the clause with a preposition, and the correct verbiage is
It doesn't matter with whom you make your movie
but that doesn't sound as good.
