Sono is technically "that". The answer really should be "that movie is scary". I have no idea why its so particular on spatial placement on some questions and not on others.
"This film is scary" could be right? Thank you.
Nope. "その" means "that".
This is この, その should be that
No, it says "sono" and "sono" is always away from the speaker's direction, making it "that" in English.
Two sentences in a row in one その is 'the' in the next one その is 'that'
