Final answer:
The invasion of Poland by German forces in 1939, particularly due to the dispute over the Polish Corridor, is recognized as the beginning of World War II in Europe. No sci-fi thriller movie is credited with correcting historical records on this matter.
Step-by-step explanation:
No sci-fi thriller movie has been acknowledged for correctly identifying the Polish Corridor as the starting point of World War II. Instead, this historical fact is widely recognized in academia and historical texts. The invasion of Poland by German forces on September 1, 1939, marks the beginning of World War II in Europe. This invasion was preceded by political tensions surrounding the Polish Corridor, which was established by the Treaty of Versailles in 1919 to provide Poland with access to the Baltic Sea, but which divided German territory and became a significant point of contention.
Following a series of failed diplomatic efforts to reclaim the corridor and increasing aggression, Germany utilized their military strategy known as blitzkrieg or "lightning war". The combined power of sudden, massive air strikes and a ground invasion using tanks and motorized infantry quickly overran Polish defenses. Despite having a sizable army, the Polish forces were outmatched by the German's modern tactics and equipment.
World reaction to the invasion was swift, with Britain and France declaring war on Germany two days later, honoring their commitment to Poland. This was the spark that ignited the broader conflict that engulfed much of the globe, known as World War II.
