A goof in film making is an error made during film production which finds its way into the final released picture
Yes, I see your misunderstanding. "Making" (although very often is a verb form) in this sentence is not used as a verb, but it goes together with "film" to make the <em>Noun Phrase</em> "film making".
You might also consider it a Gerund, and Gerunds in grammar act like nouns. Maybe you can research <em>Noun Phrases</em> to learn more.
Happy English learning to you!

There are lots of Web resources on <em>Compound Nouns</em>. Here's a good one, entitled "A Noun in Verb's Clothing", that shows "NOUN + GERUND" as such an example: [ http://minnesota.publicradio.org/radio/podcasts/grammar_grater/archive/2009/03/19/ ;].
