Although following the rule enables audiences to connect with movement in the background and visualise the scene more clearly, sometimes film-makers break the rule for good reason. This creates an effect of distortion to represent a scenario, environment or object. This is famously used multiple times in Stanley Kubrick's 'The Shining'.
Despite this, my group and I are unlikely to break this rule throughout our opening as we aim to keep the cuts smooth and consistent which means following the 180 degree rule. However, we will consider breaking this rule as we are presenting a disturbed character and environment in our opening scene.
