|Farley Granger and Alida Valli in Senso... |
Please, feel free to make funny in the comments.
But anyway. The point is, Tennessee Williams gets a screenwriting credit here, along with Paul Bowles, because he was hired by Visconti to work on the English-language version - indeed, likely the words that I could see but not hear being said. The helpful David Ehrenstein explains how this came about:
Because they just happened to be in Rome at the time. Libby Holman had run off with Bowles's Arab boyfriend and he got word that they were in Rome. So Tennessee joined him on his quest to get the boyfriend back. While trying to figure out what to do about Libby, Visconti hired them for Senso.
All that, plus the drama of art director Franco Zefferelli jealous because he though his ex-boyfriend Visconti was eyeing up Farley Granger. Cinema used to be the most fascinatingly gay place, didn't it? I sigh.
