How to revise this paragraph

The Dark Knight was the most popular film of 2008. Unlike most popular summer movies it was also considered to be a quality film and was thought to be a contender to earn an academy award nomination. Ultimately that honor was not bestowed on the film, but it's popularity and ability to elevate the comic book film, which is rarely associated with quality storytelling, remain. The film is a continuation of the direction that Batman Begins took. It showed a darker version of Batman than the one seen in the Timothy Burton and Joel Shumacher films. The core unit responsible for Batman Begins also made The Dark Knight. Specifically the director, Christopher Nolan, the writer David S. Goyer and the stars such as Christian Bale, Gary Oldmand, and Michael Caine all played a role in both of the films with the only exception being Maggie Gyllenhall replacing Katie Holmes and Heath Ledger playing the Joker in one of his last roles, which will be remembered as an excellent performance and one which earned him an academy award after he had passed away.
