The definition of "fright" from Merriam-Webster as a noun is
1 : fear excited by sudden danger : alarm
For example: He turned pale with fright.
2 : something strange, ugly, or shocking
For example: All the salons have been closed for over a month, so my hair is a fright!
Neither of those definitions seem to fit "fright movie" very well, although I can see why you thought it might work to mean "a movie that causes fright".
Let me show you how I would approach the problem.
It seems like you're pretty certain about these parts:
- He shook (probably the subject of our sentence)
- (the) scary part (adjective + noun)
That leaves us with
- with (preposition)
- during (preposition)
- of (preposition)
- (the) movie (noun)
- (the) fright (noun)
Because there are no more verbs, we are right about "he shook" being the subject. I put our remaining article as a "maybe" in front of each noun. We have a lot of prepositions to fit in the sentence and we know that we probably need a noun phrase for each of them.
So our sentence starts with
He shook
followed by some combination of the three prepositions and their nouns (lets leave the articles off for now)...
- with {scary part} / {movie} / {fright}
- during {scary part} / {movie} / {fright}
- of {scary part} / {movie} / {fright}
Which prepositions work best with "shook"? "Shook with" is a pretty common combination, but "shook during" could also work. "Shook of" isn't something we see very often, so we're going to scratch that one off.
Let's look at "with" first.
He shook with (the) {scary part} / {movie} / {fright}...
It looks like "fright" is the only option that makes sense if we use "with" first.
What if we use "during" first?
He shook during (the) {scary part} / {movie} / {fright}...
It looks like the only option that doesn't make sense is "fright", because fright doesn't have a duration like a movie or a scary part does. We can be pretty sure that "with" and "fright" go together now.
So maybe "of" can help us choose whether "during" goes with {scary part} or {movie}. We know it probably doesn't go after "shook" so it will go after the phrase after shook.
He shook {with fright} of (the) {scary part} / {movie} during (the) {scary part} / {movie}
"He shook with fright of ___ " doesn't work because we usually just say "shook with fright" without more description, so the preposition after "fright" is probably "during".
He shook {with fright} during (the) {scary part} / {movie} of (the) {scary part} / {movie}
It doesn't make sense to say the movie of the scary part, so our result is:
He shook with fright during the scary part of the movie.
or maybe even
During the scary part of the movie, he shook with fright.
