What are your thoughts on James Earl Jones giving license for his voice after his passing for Disney to use for Darth Vader? Or Proximo having a final scene added in the movie Gladiator upon the passing of Oliver Reed during production? I see both of these as entirely valid use cases, but I'd be curious to know where you stand on them / why you might think recreating the actors here would be detrimental.
