A random YouTube search brought me to this gem this fine evening.
This is a trailer for the 2010 movie Black Swan starring Natalie Portman and Mila Kunis. Here's the kicker, this is made up of clips of Aliya Mustafina and Viktoria Komova. Viktoria is Natalie Portman character, Nina and Aliya Mustafina is Mila Kunis's character, Lily. Also making an appearance are, Vera, Viktoria's mom and Alexander Alexandrov.
If you've seen Black Swan, this will be totally hilarious to you, if not, then rent the movie, and then watch this trailer. I'm still waiting to see a trailer for Hunger Games with all gymnastics clips.
