If a live-action Dragon Ball movie is to be made, the cast of Goku must be done with utmost care. The last attempt at a live-action adaptation, Dragonball Evolution, was a complete failure.
However, if the filmmakers can learn from their mistakes, there is potential for a successful movie. And the key to getting it right is the character of Son Goku, the lovable, emotional, and energetic Saiyan at the heart of the franchise. He has a kind and compassionate side, as well as an incredibly powerful and skilled warrior.
There are several actors who could bring Goku to life, but Andrew Koji is one of the most suitable options. Koji has already demonstrated his physicality and martial arts skills in films like Bullet Train, Snake Eyes, and Warrior, making him an excellent choice for the role.
Another strong contender is Simu Liu, who has already proven his action chops in films like Too Eager and Shantaram. His range and physicality make him a strong contender for the role of Goku.
Manny Jacinto is also an acting talent to be considered, having already shown his action hero credentials in The Acolyte and The Good Place. He has a versatility that would be an asset in bringing Goku to the big screen.
All three actors have the potential to bring Goku’s unique mix of action, drama, and humor to life. If the right actor is cast, a live-action Dragon Ball movie could be a huge success.
