What defines a film as a 'blockbuster'?

A film is defined as a 'blockbuster' primarily by its high production budget and massive appeal to a wide audience. This term originated in the mid-20th century to describe films that not only invested significantly in production values, such as special effects, sets, and well-known actors but also achieved substantial box office success. The appeal of blockbusters often extends beyond niche audiences, aiming to attract viewers from various demographic groups, making them significant contributors to a studio's financial success.

The emphasis on both a high budget and broad audience appeal distinguishes blockbusters from other types of films that may excel in critical acclaim or artistic expression. While options discussing critical acclaim, artistic focus, and limited theater availability reference important aspects of cinema, they do not align with the commercial criteria that define a blockbuster. Thus, understanding the characteristics that lead to a film being labeled a blockbuster helps in recognizing the broader trends and economic considerations in the film industry.
