He mentions that it took five years to get the film financed and that he finally found it from the owner of PayPal of all places. He speaks very eloquently about how certain scenes came together and the challenge of achieving certain shots. Reitman also touches upon the things that he changed from the book that it was based on and why. There are frequent lulls in this otherwise solid track.

Also included is an additional commentary by Reitman and actors Aaron Eckhart and David Koechner. The track starts off a little too self-congratulatory as everyone praises each other. There is also some overlap from the previous commentary. Fortunately, Koechner keeps things light and asks Reitman questions about the film to keep things going. Eckhart doesn’t speak too much, offering occasional anecdotes about filming.

A pretty solid commentary that hits all the right notes. He explains a lot of the backstory of the making, different scene versions that didn't happen, motivations of characters, how characters were developed and what they meant.

It definitely adds to the enjoyment and understanding of the film.
