This master's thesis analyses feature films and TV series released during the 100th anniversary of the First World War (WWI) and produced in West European and English-speaking countries. The analysis can be divided into a few categories. Namely, the focus of the second chapter is on a miniseries called 37 days, more specifically on its portrayal of the major historic figures that took part in the diplomatic negotiations which took place between the assassination of Archduke Franz Ferdinand of Austria and the start of the WWI. The third chapter discusses the portrayal of the battlefield, warfare and, furthermore, the conditions in trenches and military hospitals. Here, various aspects of WWI participants' lives will be described, such as food, combat, everyday life and even the relationship between the medical staff and the soldiers. The last chapter of this research paper will touch more upon the emotional aspects of the war. They can be best examined through depictions of the protagonist and the antagonist, or the hero and the enemy, as well as through different types of brutality and the meaninglessness of war. A special insight will be given into the so called shell shock, a type of post-traumatic stress disorder, and the disparate and often controversial interpretations of the Armenian genocide. Finally, the aim of this thesis is to point out the similarities, as well as the differences, between the different portrayals of the aforementioned aspects of the WWI by comparing the movies and TV series released for its 100th anniversary.
