The Star Wars: A New Hope novelization provides an look at the film from a slightly different angle. The book came out in 1976, prior to the film itself, and therefore is based on an earlier draft of the script. It includes characters and scenes that were cut from the movie. It is definitely a fun read to see how it differs from the movie, and to imagine how a number of readers in the 70s may have first experienced Star Wars.
Luke Skywalker Challenged the Stormtroopers of a Distant Galaxy on a Daring Mission—Where a Force of Life Became the Power of Death!
Farm chores sure could be dull, and Luke Skywalker was bored beyond belief. He yearned for adventures out among the stars—adventures that would take him beyond the farthest galaxies to distant and alien worlds.
But Luke got more than he bargained for when he intercepted a cryptic message from a beautiful princess held captive by a dark and powerful warlord. Luke didn't know who she was, but he knew he had to save her—and soon, because time was running out.
Armed only with courage and with the light saber that had been his father's, Luke was catapulted into the middle of the most savage space war ever...and he was headed straight for a desperate encounter on the enemy battle station known as the Death Star!
The Star Wars: A New Hope novelization is an interesting one. Originally released before the film premiered, the novel is based off the George Lucas screenplay and includes a number of lines and scenes that never made it into the final film. It was definitely a fun read to see how it differed from the film itself. However, the writing never fully gripped me, and, as far as film novelizations go, this is definitely on the weaker side. For Star Wars fans, though, it's worth the read to see the ways the film diverted from the original story.
