No clue, it's just a personal guess. I know there are several things
related to this word; My only reference is that Okrand usually refers to
older films from that time period. It's more likely than that he thought
of the 2007 novel.

But why isn't the *word itself* a sufficient pun? 

If I was told that it is indeed a Hollywood reference, my guess would've been the musical by that name, which tells the prequel to Hamlet:

But I don't think anything other than the word "skullduggery" itself is needed to explain the pun.
