Lorenzo, who has developed many useful Ubuntu tools (appindicators, lenses, etc.), has released yet another cool Unity lens with previews support: a Movie Lens.

The Unity Movie Lens can be used to search for Movies and using the Previews feature (which can be accessed by right clicking on a search result) available in Ubuntu 12.10, you can see various movie information like the movie cover, rating, genre, artists and a movie description.
