Blockbuster films are high-budget movies that typically generate significant box office revenue. They often feature popular actors, impressive special effects, and engaging storylines designed to attract large audiences. These films are usually released during peak seasons, such as summer or holiday periods, to maximize viewership. The term "blockbuster" originated from World War II when it referred to bombs capable of destroying entire blocks of buildings. Today, it describes films that achieve massive commercial success, like those in the Marvel Cinematic Universe or Star Wars franchises. Such films often lead to sequels, merchandise, and expanded media.
