When physicist Leonardo Vetra is murdered and branded with the word Illuminati, his boss, CERN director Maximilian Kohler, asks Harvard symbologist Robert Langdon for help. Brown states on his website that his books are not anti-Christian, and that he is on a "constant spiritual journey" himself. Brown's novels that feature the lead character also include historical themes and Christianity as motifs, and as a result have generated controversy.

Langdon is portrayed as a Harvard University professor of religious iconology and symbology, a fictional field related to the study of historic symbols, which is not methodologically connected to the actual discipline of semiotics. The Robert Langdon book series is named after Robert Langdon, the protagonist of the novels by American author Dan Brown.

If you want to check out Robert Langdon in action before you spend money on seeing Inferno on the big screen, you'll want to re-watch the first few movies, below.Box set of the first four books in the series with their British covers But, Langdon isn't just any old Professor - he's done this before. Sounds like a lot to ask of a history professor, if you ask me. With a little help from a nice doctor (Felicity Jones), Langdon tries to solve clues left in Dante's Inferno in an attempt to stop a world-wide plague meant to curb the Earth's population. This time, instead of finding clues in the Mona Lisa, Langdon wakes up in an Italian hospital, having no memory of why or how he got there. In the new film, Langdon will face a brand new, non-Da Vinci themed threat.

But before you start re-watching these films any way you can, first learn a bit about Inferno. The Da Vinci Code is, but Angels & Demons is not. But, are the Da Vinci Code movies on Netflix? Because, if not, it's gonna take Professor Langdon to magically figure out how you can watch them. Now, Langdon is ready to save the world from a plague inspired by Dante's inferno in, but before he does, you might want to check out the other two movies first. Langdon, as played by Tom Hanks, first entered the business of world-saving in 2006's The Da Vinci Code, tradition he continued in 2009's Angels & Demons. In Inferno, everyone's favorite historian/world-saver is back to save the planet in another movie based on the work of author Dan Brown.
