The group chose the title "Calibre" for their film as it fit with the action genre and they found other independent films had used similar titles. They began the film with an action scene within the first two minutes to set the tone. Throughout filming, they used match-on-action techniques and developed shots based on action genre research to make fighting and shooting scenes look realistic and immersive. They purposefully crafted the storyline to deliver high-energy action and thrills to attract their target audience.
