I was perusing some Simpsons clips this afternoon and came across a story to the effect of "So and so didn't want to play himself, so Dan Castellaneta did the voice." It's a good impression and people didn't seem very upset about that. I am not sure how this is different. (Apparently this particular "impression" predates the Her character, so it's even easier to not be mad about. It's just a coincidence. They weren't even trying to sound like her!)

I read a lot of C&D letters from celebrities here and on Reddit, and a lot of them are in the form of "I am important so I am requesting that you do not take advantage of your legal rights." I am not a fan. (If you don't want someone to track how often you fly your private jet, buy a new one for each trip. That is the legal option that is available to you. But I digress...)

That example isn't really pertinent, because in the case of the Simpsons it's fairly certain that the actors and actresses sign away the rights to their likeness to the company, otherwise there'd be major issues if one ever quit, became unable to work, just wanted a bunch of money, or whatever. There's probably some poor analogy with how if you write software, your company [generally] owns it.

For something more general look at Midler vs Ford [1], and lots of other similar cases. Ford wanted to use get Midler to sing some of her songs (that Ford owned the copyright to) for a commercial. She refused, so they hired an impersonator. They never stated it was Midler in the commercial, but nonetheless were sued and lost for abuse of 'rights of personality' even for content they owned the copyright to! Uncopyrightable characteristics highly associated with a person are still legally protected. Similar stuff with fight refs. Various trademark lines like 'Let's get it on!' or 'Let's get readddy to rumble.' are literally trademarked, but it's probably not even strictly necessary since it would be implicitly protected by rights of personality.
