Analysis of information sources in references of the Wikipedia article "Capote (film)" in English language version.
While an unattributed comment in Clarke's biography suggests that money changed hands, there's no evidence that it went to the warden
The only evidence for Capote having bribed his way into Death Row is a quote (unattributed, but apparently from Capote) in Clarke's biography: "I went for broke and asked for an interview with this behind-the-scenes figure, who was a man of great distinction and renown in that state. 'I'll give you ten thousand dollars if you can arrange this,' I said. … I guess my offer was very tempting, and he just nodded his head."
In real life, he did not spend days and weeks with Smith, as the film implies. Most of their relationship was conducted by letter. Yet the film does capture and explore the peculiar tenor of that relationship. The powerful scene in which the betrayed Smith yells at Capote, "What's the name of your book?" is based on a letter the real Perry Smith wrote to Capote on 12 April 1964: "I've been told that the book is to be coming off the press and to be sold after our executions. And that book IS entitled 'IN COLD BLOOD.' Whose [sic] fibbing?? Someone is, that's apparent."
