Very minor spoiler, so be warned if you haven't seen this 25 year old movie.

[Show spoiler]When Joker comes out of the shadows right before he shoots Jack Palance's character you can see a purple smudge on Jack Nicholson's neck.
This is because in the process of filming some of the Joker face paint rubbed off onto the coat he was wearing, to fix this the filmmakers just put some purple shoe polish over the makeup. Some time later Jack must have sat down or something and the polish rubbed onto his neck and ta da purple smudge.
