Final answer:
In creating a shooting schedule, the script's genre typically has the least impact compared to factors like actor availability and location access.
Step-by-step explanation:
When building a shooting schedule, various factors can impact its development such as actor availability, location access, time of day for specific lighting needs, and weather conditions. However, the factor that generally has the least impact is the script's genre. Whether it's a comedy, drama, or horror, the genre does not significantly dictate the scheduling logistics as much as the other practical considerations do. It is essential to prioritize logistical and resource-based considerations to ensure a practical and effective shooting schedule.
