베이포머의 특수효과에 참여한 Scott Farrar와의 인터뷰 기사

SF: Just building him, for one thing, never in your wildest imagination, did you think the color red would be so hard to duplicate in all the different lighting scenarios that we have in the movie. Basically, he's a red that is copied after this sophisticated fire truck. But trying to nail down a color; the sheen of a color; the sheen of the bounce of the light on the color. All these different artifacts that happen: whether it's sunlight or fluorescent lights or what have you. And the color red is one of the hardest there is in computer graphics because it goes purple or pink or green, so you're always fussing with each and every shot.  Then just as a key character we came up with all kinds of ideas: this beaded beard so it would wiggle with every move or talk. And we did our initial test with Sean Connery before any voice actor was cast. And then we have to have the facial design feel like it's a face and that means hundreds of moving parts on the face because they're just hard body surfaces. And if we don't have enough pieces, we put more pieces in and we do that practically every time, and then you usually have to plus out the eyes because you can't really tell all the nuances of the expressions. So we got that nailed. And then we cast Leonard Nimoy, and it wasn't far from the look of Sean Connery. So we made only a few minor adjustments on the face.

오피셜로 센티넬의 얼굴은 배우 캐스팅 단계 전에 숀 코너리를 모델로 했고, 레너드 니모이가 캐스팅된 후엔 얼굴에 수정이 가해졌는데, 그다지 많이 변하지는 않았다네.
