This is being referred to as a "live-action" remake of the original animated Lion King. However, CGI is still another version of animation. Unless the filmmakers are truly using real animals to play the parts, this film is an animation.

Mufasa: Everything the light touches... is our kingdom. But a king's time as ruler rises and falls like the sun. One day, the sun will set on my time here, and will rise with *you* as the new king.
