GK: As a fan of the show, you get attached to the characters, and because it’s animated, the voices. I’ve always wanted to know what happened to Nia Long as Roberta. She seemed to have disappeared halfway through. What happened there?

MH: Yeah, I’ll tell you what. The first time I ever saw Nia Long on screen, I was – as we all were – in love. She came in to read for Donna [voiced by Sanaa Lathan] and Roberta [now voiced by Reagan Gomez-Preston] and she was great. I really liked her. I think it came down to, and this was not my decision or our decision on production, people with the checkbooks felt like she sounded too old. That’s the bottom line. After the first 13, we recast. To this day I love running into Nia, there is nothing but good feelings. It’s one of these things. When I’m a multimillionaire making my own projects I’m gonna keep whoever I want. But I absolutely love what Reagan is doing and she sounds like the teenage girl that we need. On “Family Guy” that’s not the first Meg … it’s part of the process. I’m extremely happy with Reagan and I’m privileged to have been able to work with Nia.

Not a surprise The Flintstones went through voice changes. I like the current Meg best.
