According to my own amazing trivia knowledge (and a quick search), the answer is actually two actors. Jeremy Bulloch was the guy in the suit, but Jason Wingreen did the voice. Neat!

When attempting to deduce something, there are times when the number of things that could technically be the answer are too many to be helpful.

For example, if you're trying to figure out simply who could have done something, the number of suspects is potentially going to be very large. You have to narrow that number down somehow with things like motives and additional evidence.

I bring this up because some people were asking why Sarah was concerned with the shape of the magic mark when the shape doesn't actually determine what the spell is. She doesn't really have a lot to go on, and "it could be anything" isn't particularly helpful regardless of whether it's technically accurate. She may as well see if she can figure something out based on the assumption that it might be an intentional clue.

None of that is particularly amusing, however, so let's all collectively go to our happy imagine a 60's era Adam West as Boba Fett and talking to Darth Vader.
