Fan Casting The Eternals (MCU)

The Eternals are a powerful race of cosmic beings who have existed in our solar system for millions of years. While most Eternals look perfectly human on the outside, their advanced biology gives them incredible strength, long lives and powers that set them far above mortal men. Both the Eternals and their genetic cousins, the Deviants, were created by the cosmic gods known as the Celestials through experiments on early proto-humans. And where most Eternals have chosen to follow the path of peace, the Deviants are hateful and warlike, with their hideous outer appearance reflecting their twisted inner nature. The two races have been locked in a never-ending war since those early days, with humanity sometimes paying the price.
