Taglines

Taglines used of horror/thriller films are often very personal and used in such a way to make the audience feel personally affected by the film. After looking at real taglines I have complied a list of protein tailgates for my film; The Room. 

1. Would you let them in? 
2. One door closes... 
3. Could you handle the truth? 
4. Would you go back? (if sequel) 
5. All it took was three knocks. 
6. How many secrets can one room hold?
