Posters are an important part of a film's marketing campaign – they serve as a means of enticing audiences to the cinema, and give hints at what cinemagoers can expect when it comes to the film's plot, genre, key cast and tone. Posters are also tailored to the country the film is releasing in, so the poster for an Australian theatrical release could vary greatly from the film's poster in France, the US, or Japan. This Polish poster for 1978 Australian feature Blue Fin is a prime example of how different a poster can be from region to region. This version, while still visually striking, depicts a Southern Bluefin Tuna as a giant, nightmarish piranha, which feels unsettling and wildly off-base for a family-friendly film about a fishing trip. The Australian poster, in comparison, depicted a father and son, and leaned into Blue Fin’s connection to local box-office hit Storm Boy (1976), which was also based on a novel by South Australian author Colin Thiele and shared the same screenwriter (Sonia Borg) and star (Greg Rowe).
