This is what threw me when I first heard about this, Roland is like 6.5ft tall at minimum, Kevin Hart is like 4ft tall, even with prosthetics, risers, creative film angles, etc we will know how tall he really isn’t and it will break the illusion.
I hadn’t even thought about the voice. Holy shit you’re right, that’s going to be bad unless they auto tune it to sound more like game Roland. Though I fear they will lean into his voice and it will be horrendous.
