Production company logos are typically shown at the beginning of films and trailers to advertise the company. The logos can be complex clips up to 30 seconds with sound or simpler still images. When creating a logo, it needs to be unique, not overpowering, and clearly incorporate key elements to fulfill its purpose of representing the production company. Logos should be bold, use typical colors like blue or black, have a clear central name or logo, and be either simplistic or more complex with images related to the company name to uniquely identify the producer.
