Indeed, Peter and Frank were on hand at this show, and were asked at their panel of their thoughts concerning non-union actors being used for the Siege Netflix series to impersonate their voices: Yusuf FINALLY GOT THE DELTA SQUAD MEGAZORD on Twitter Transcript for the video: Q: You guys are excellent, your voices are so iconic. How do you guys feel about other actors taking on that role and then trying to sound like you guys? FRANK WELKER: You know, it's funny; uh, it's kind of an unwritten law in the business that we come from, where when we grew up in business, is you just don't do that. You never take over anybody's voice who can't do it themselves. You just don't do it. But... [Frank motions to Peter.] PETER CULLEN: Yeah, it's grand theft! [The audience laughs.] Yeah, that's happening now, with Netflix; they're, uh, gonna produce a Transformers series that they're not going union, and...you know, we work in our union. You know, that's what protects us all, as actors, you know, and when other guys go underneath that, and, uh, they literally are, you know, they're, they're destroying our union from the outside, with subterfuge; it's wrong! It's wrong, but that's what's gonna happen with the series, there'll be someone else doing Optimus Prime, and that hurts! That hurts. [Audience boos.] Yeah, don't let it happen! Get on Netflix! They're bad, that's not nice. [Does a "shame, shame" motion with his fingers.] FW: But, ultimately, we do everything for you, so you're, you're the, the audience, you're the power, so what you want will ultimately be the end, so you decide what you want, and hopefully it's good.
