To pay homage to an actor and comedian such as George Burns would be a great honor for a lot of actors, but it would definitely take the right individual to make the part work, and yes, size would definitely be an issue, as would appearance. In the PC world Burns would still need to be played by a white individual since woke or not, depicting the character that Nathan Birnbaum would one day become requires that his legacy be taken seriously and given as much respect as possible. With such a legendary career as that which George Burns created, the idea that he could be played by anyone and be given the proper respect is easy to imagine, but what might happen is anyone’s guess. Burns was the type of individual that wasn’t bound to take things too seriously unless he had to, and he had the ability to entertain a wide number of people while alive, so it will take someone that can do the same. There are plenty of actors out there that have the kind of charisma that’s needed to make this happen, but in terms of size, there are only so many that would really be able to measure up to Burns.
