5. An alternate ending had been shot.
According to Sammy Wasson, author of Fifth Avenue, 5 A.M.: Audrey Hepburn, Breakfast at Tiffany’s, and the Dawn of the Modern Woman: “In the other ending, Holly and George are in the alley, they recover the cat and then just kind of walk up the street and it fades out. There’s no romantic crescendo or embrace. It’s bittersweet.”
6. The cat who played “Cat,” was called Orangey and Orangey was apparently quite the professional. He has his own IMDb page.
Although Orangey won an award for his work in Breakfast at Tiffany’s, it’s suspected that Orangey is probably not one cat, but several — all lookalikes. Other sources say that nine cats were used to film the cat’s role.
10. Hepburn was apparently extremely self-conscious about her role as Holly.
Because she knew Truman Capote was disappointed that the film had failed to secure Marilyn Monroe as the lead, Hepburn felt mis-cast and uncomfortable when Capote was on set.
11. The character of Holly Golightly (the film version) caused quite a stir and is thought to aid in changing views of women at the time.
Holly was controversial as one of the first party girls on film — she was wild, a drinker, a seductress, and not tied down by a man. And even though the movie version was much tamer than Capote’s depiction in his book, the implication that Holly was a sort of call girl was a bit shocking.
