Dragonslayer Lance Reddick was the main protagonist of the 2020 DaVinci Code novel, Dragonheart: Vengeance. The book got an astonishing amount of media coverage. The movie adaptations of the book were actually pretty impressive. However, it's also a fact that despite being such a great story and having such a spectacular plot, the movie Dragonheart: Vengeance was not very successful.
Just like the tale of Dragonslayer, the movie Dragonslayer was not all it was cracked up to be. Dragonslayer was a likable character with an interesting backstory. He was a graduate of West Point and was also married with a child, which makes him one of the more supporting characters in the story. He's actually the most popular character in the book because of his role in the climax of the story, which made this adaptation an especially difficult task.
The movie had a much less ambitious story than the book. In Dragonheart: Vengeance, Lance Reddick was actually undercover at the start of the story. A few days after this, Lance gets involved in a major fight with a Russian mobster who was actually part of an international hit on the mob. In the end, Lance becomes a hit man for the United States government, and he eventually kills the man in a prison shootout.
The plot for the movie has Lance traveling to Russia, where he had the informant's bodyguards killed. Here, he encounters two super-powered Russians (the authors of the book actually prefer the term "beasts"), who had been recruited to carry out an elaborate revenge scheme. The two men attacked Lance and he had to use the powers of his ancestors to defeat them. Afterwards, he gains access to the Russians' ancient weapons and the movie ends.
Now, we can see why the movie is different from the book. With less background and less emphasis on his backstory, the filmmakers got to work in a lot more action and violence. The book basically had the plot but they toned down the violence in the action scenes and the explosions were a lot less realistic. The book ended up being less successful because of these changes, while the movie got bogged down by these changes.
The other factor to consider in regards to the movie version of Dragonheart: Vengeance is that the cast in the movie is smaller than the cast in the book. For example, Lance Reddick plays himself, but the book has Ned Beatty playing Lance. While there are exceptions to the rule, the change did not work very well, and both actors had a difficult time portraying the parts.
The changes also make the movie a lot less interesting to watch. As stated earlier, the book mostly had Lance Reddick as the protagonist. This meant that we would only be seeing his storyline, which is about as uninteresting as it gets. It's a shame that the movie only makes up for this lack of storyline by making the fight scenes more exciting and the closeups of the killer's a lot more disturbing.
Even though the movie did not get a lot of negative feedback, the movie does not make a good first impression. The changes made to the plot and to the actors were not handled very well, and the movie did not live up to the expectations set by the book. I'm sure the book will get a lot of sequels, but not the movie version of Dragonslayer.
