We are presented with 24 movie screenshots and blanks. As hinted at by the title, in each scene there is an offscreen character holding onto the depicted character for dear life. The name of this character always fits into the blanks, so we fill in the names and take the boxed letters:
The boxed letters spell out SEVEN PEOPLE WILL BE RESCUED. Of these 24 characters, 7 of them are pulled up and saved, while the other 17 are let go for various reasons and die (or appear to die, in the case of Loki and Kludd). The 7 rescued characters are highlighted above, and their letters spell out the answer SPOILED.
This puzzle idea was originally inspired by watching the relevant scene in Legend of the Guardians, which felt so shoehorned in that it reminded me of other variations on this trope, especially in various Disney movies.
At some point I thought it might be fun to have the puzzle involve matching up similar instances of this trope from different movies, as there is a very large variety like “hero saves villain and villain becomes good”, “villain deliberately lets go because they don’t want to be saved by the hero”, “hero tries to save villain but villain attacks them and dies because karma”, etc. However I figured there might be too much subjectivity and eventually settled on this extraction after coming up with a reasonable cluephrase that included the answer as a subsequence.
