Are titles of films carefully chosen to be short and have only one possible meaning?

Not necessarily. Film titles can vary in length and may have multiple interpretations or meanings. While some titles may be short and straightforward, others can be longer and more complex. The choice of title depends on various factors such as the genre, theme, and intended audience of the film. Ambiguous or multi-layered titles can create intrigue and curiosity, inviting viewers to explore different perspectives and meanings within the film's narrative.
