7. Kirsten Dunst - The Bling Ring
Sofia Coppola's The Bling Ring, which starred Emma Watson as one member of a gang of teenagers who get their kicks robbing the houses of famous people in L.A., was based on a true story - celebrities like Paris Hilton and Orlando Bloom really did get their homes broken into in all the ways that the movies depicts. To add some major authenticity to the movie, Hilton herself even made a small appearance and let Coppola film in her actual house. As the teens in the movie become more and more wealthy as a result of their criminal activities, they start hanging out at cool clubs, which leads them into one very, very brief celebrity encounter. That's to say, pay attention during the club scene and you'll hear one of the characters say: "Hey, that's Kirsten Dunst," at which point we're treated to an incredibly quick shot of Kirsten Dunst standing across the room. Kirsten Dunst and Sofia Coppola have worked together on multiple movies, of course, which explains why - and how - this happened. Blink and you'll miss it.
