Not in the "entertainment" domain, but Malala Yousafzai's my core one. https://en.wikipedia.org/wiki/Malala_Yousafzai https://www.ted.com/talks/malala_yousafzai_what_i_got_wrong_about_changing_the_world
Angela Davis, for her spectacular guts in writing "Race, Gender, & Class", or whatever that book is called. https://en.wikipedia.org/wiki/Angela_Davis
Robin Williams always insisted on movies he was in hiring homeless people, & he corresponded with fans who were being crushed by depression, carrying their lettres when he was in their area.. https://www.ted.com/talks/samantha_cohen_robin_williams_and_the_struggles_inside_us She never mentions the KEY point with many comedians: it is when one knows darkness sooo profoundly, that fighting it off of other's-lives is a fundamental-NEED, that one gets like the more intense comedians, like Williams. It is because of being embedded in darkness that one fights to-the-death for light's life in others' lives.
There are a number of people who've done TED Talks who deserve all their fame, if not more..
& Rupert Sheldrake, for calling-out the scam Scientism is, AND for calling-out the scam that TED is, too. https://www.youtube.com/results?search_query=rupert+sheldrake+anniversary is the guy, but the exact video, the 10th anniversary ( or something like that ) of his TED Talk being banned, seems to have been disappeared.
( other TED Talks they've banned include Russell Targ's one on remote-viewing https://www.youtube.com/watch?v=_KB9Z6BcvZg , & Targ's a physicist, not a woo-pusher, & yes, for anybody who'd dug into that stuff, the CIA actually had employed Ingo Swann, the remote-viewer, possibly the best ever, & Joe McMoneagle was also one in that line of work https://www.youtube.com/watch?v=F-8puX-83o4 ..
.. & whats-his-name, the guy who does archaeology talks, but changes how aligned with UFOs he is, depending on the audience, from what I've read.. Graham Hancock: his banned TED talk was on how Ayahuasca kicked his ass, because he had been indulging in dope. https://www.youtube.com/watch?v=Y0c5nIvJH7w should be the same one I saw years-ago. )
I'm seconding the Tom Waits vote, the Greta Thunberg vote, & the Keanu Reeves vote.
