I mean... I know many of the answers on mine are fairly obscure. I featured a mix of celebrity actors who have done a voice or two, like most of those above, and actual "voice actors" who make their living doing voicework... most people simply don't know or care about the real voice actors.
I've seen most of them with my grandkids, but didn't remember who was doing the voice work for most of them. Still managed to get 9 correct. I couldn't imagine that Darth Vader didn't command 100%. I think I've slipped another generation behind.
I had absolutely no idea who voiced Darth Vader until it was a question on a different quiz a few weeks ago and Star Wars came out when I was 10. Some of us just don't have the faintest interest in it
Did better than I expected (17/20), given that I haven't seen more than half of these. Got half a dozen just by guessing famous comedians with distinctive voices and common last names!
