This video tutorial on the simulation of an anamorphic look is divided into two parts: In the first part, the Bookeh is made with gaffer tape and scissors.

The second part is about the post-production, where a new flare plugin is used (MFlare 2), which as far as we know is only available for FCPX (and motion) at least at the moment. Actually a quite normal flare plugin like there are many others - but thanks to the built-in tracker and the coupled intensity automatics it is quite helpful. Here is the video clip of Brandon Li:
