 The line "Watch out, Haskell, its real!" was actually dubbed in  after the shooting. It was supposedly what Haskell Wexler (qv) was  thinking to himself and he wanted to include it. Verna Bloom (qv)  literally stands out in the film because of her yellow outfit. Bloom  said she picked the outfit because she thought her character, a  woman of modest means, would wear something like that. It just  happened to contrast with what everyone else was wearing, so you  notice her.
