Why Some Movies Use CGI While Others Don't

Our modern era of filmmaking is dominated by the use of computer-generated imagery (CGI), with most major and minor studio films and television series from Netflix, Prime, and HBO Max featuring CGI elements. It is almost impossible for an untrained eye to distinguish between CGI and in-camera footage, especially when the film or series has been produced by experienced professionals.

The Role of CGI in Filmmaking

CGI, or computer-generated imagery, can be utilized in a wide variety of ways in films. It can be used to create characters, objects, props, environments, and special effects. The decision to incorporate CGI elements is often based on the visual enhancement and story development it can provide. However, practical limitations such as cost and logistics may necessitate the use of CGI rather than real-world elements.

Practical Limitations and CGI Solutions

Filming certain elements can be particularly challenging and costly. For instance, shooting wild animals can be extremely difficult and expensive. If the film or series requires the presence of such animals, the crew may opt for CGI animals instead. This not only simplifies the production process but also enhances the final product by allowing for greater creative control and visual representation.

Popular Uses of CGI in Filmmaking

There are various situations where CGI becomes indispensable in the filming process. Some common uses of CGI include creating impossible landscapes, enhancing character designs, and generating dynamic and complex special effects that would be practically impossible to achieve through traditional means. For example, a film set in a fantastical world, such as a magical realm or a distant galaxy, might heavily rely on CGI to create believable and visually stunning environments. Similarly, characters with superhuman abilities, such as flying or shape-shifting, would be far easier to execute through CGI than through live-action shots.

The Cost-Benefit Analysis of CGI

While CGI can provide numerous benefits, it is important to consider the cost-benefit analysis. One of the primary drivers of CGI use is the potential cost savings and logistical benefits it offers. For instance, a feature film that requires micro-explosions, dramatic seismic shifts, or intricate set pieces would likely be more cost-effective to produce using CGI. Additionally, CGI can be reused, which can save time and resources in subsequent films or series within the same universe. For example, a film series set in a futuristic world can use the same CGI elements in multiple films, reducing the need for repeated production and filming.

Real-World vs. CGI: An Example

Let's take a specific example to understand when CGI becomes indispensable. Consider the movie Moonlight. While it contains no complex CGI elements, the film leverages CGI in a different way. The film focuses on the emotional journey of a young black man in Miami. The use of video projections and modified lighting during certain scenes helps to convey a more abstract and dreamlike atmosphere. In contrast, films like The Matrix and Guardians of the Galaxy rely heavily on CGI to create their vivid, otherworldly environments and intricately designed characters.

Conclusion: The Future of CGI in Filmmaking

As technology continues to advance, the use of CGI in filmmaking is unlikely to decrease. In fact, we can expect to see more sophisticated and seamless integration of CGI elements in future productions. The key to successful CGI use lies in the careful balance between creative vision, practical limitations, and cost considerations. Filmmakers who can effectively utilize CGI will continue to produce visually stunning and compelling films that captivate audiences.
