Sometimes when you do searches at Google, the auto-complete suggestions offered in the search bar may show additional snippets of information. Most people don't really take notice but I think Google has been doing this for several months now.
Philipp Kloeckner spotted a recent on for a search on Casablanca but just by typing in casa and posted the screen shot on Twitter. I was able to replicate it and took the screen shot above, which is a bit higher resolution.
As you can see, Google is showing three auto-completes for that term, one for a generic search, one for the film and the last for the city. Each would give you a different set of search results.
Try it yourself.
