How accurate are Milk and Frost/Nixon?

Specifically, in Milk, the narration comes from the tape he made prior to his death. Are all the words he spoke in the movie from that tape? Or, did the screenwriters take some license with it? Likewise, the dialog that is spoken in the tv segments in Frost/Nixon - were they verbatim from the broadcasts, or did those screenwriters also modify? xo, C.

bump Wait - no one in this forum knows the answer? Do I have to go to GQ? wow

I didn’t see the movie, but here’s the tape:

And here’s an interview with the writer, whre he says the following:

The writer of Frost/Nixon said in an interview I heard on NPR that one key scene, where Nixon calls Frost on the phone, was entirely dramatic.

F/N obviously could not JUST be scenes from the interview or there would be no need to make the film.

Yes, this I understand, of course. But there are no doubt scenes in the movie of the interviews. Are those verbatim?

From a longer article detailing the historical inaccuracies of F/N:

Very nice find. Thank you.
