Man with Bernie you're gonna have pull a Jamie Foxx as Ray performance.
Jamie Foxx brought his essence to the screen. Him nailing the look was an added bonus but he bodied that shyt
With Bernie I'm not looking for a impersonation, or a look alike. You need to bring that essence to the screen. Dont sound and act like Bernie, BE Bernie.
From his mannerisms and facial expressions to the way he walks and carries himself.
Cant think of any comedians alive that can pull that off. You're gonna have to find a unknown imo.
