We never would have heard of "Closing the Ring," the movie that shows Mischa Barton's boobs if it weren't for the fact that it's the movie that shows Mischa Barton's boobs. In case you don't want to see the movie, we have a screen grab and a link to the (NSFW) video after the jump.
2007's "Closing the Ring" tells the story of a young man trying to return a ring to a WWII bomber pilot. In case you don't want to watch the entire thing to see Barton's boobs for 45 seconds, The Sun has the clip.
