Is that Jensen character supposed to be Capote?

This movie is great – movie Capote couldn’t improve on the final hanging sequence, so they just copied it. And this film has a way more riveting Clutter murder scene, the murder and its violence are way more important too, less gratuitous than in Capote. Almost as good as the book . . .

Film has a references to Sierra Madre . . . does the book? I don’t remember, but I guess I’ll try to search inside at Amazon . . .
