Generally, we're hired for any job because we're good actors, not because we're necessarily fans of the project. Given the choice, would you prefer the characters you love be voiced by a superfan whose acting talents span the spectrum from A to B, or by a professional actor who can spend an hour or so in the studio and give a credible performance before moving on to the next gig on the agenda?

Obviously a good experienced voice actor like Mr. Pollock can make a character feel real and more enjoyable rather than a fan that is inexperienced and amateurish. Most actors are given a background on a character before they do work so they understand where the character is coming from. Most actors are very thankful for the opportunity to have a job and respect that fact but that doesn't mean they have to be a 'superfan' of the show to have a good performance.

Speaking of Best Wishes, I was the one who asked the BW question!
I read the interview, and I will say it's good.

I agree with your opinion.

I'm surprised I'm not seeing more responses from the people who submitted the questions we used! :-P

does that, somehow or other, explain the video being divided almost two minutes before the "welcome back" dialog came up?

That was a YouTube problem at the time that didn't allow for video to be greater than 15 minutes. They have since begun activating some accounts without the time limit to a select number of users.
