First Blood
David Morrell, author of the original "First Blood" novel, wrote novelizations (book adaptations) for the first two "Rambo" sequels. Morrell has said that he wrote the novelizations because he wanted to include characterization that he felt wasn't in "Rambo: First Blood Part II" and "Rambo III". Morrell did not write a novelization for the 2008 film, "Rambo", as he felt the film's characterization matched that of the original "First Blood" novel.
