Films produced and/or distributed by and/or marketed to Christians featuring content that promotes Christianity and its tenets through attempting to strike fear in the hearts of their audience. Most of these are apocalypse-themed, others are smaller in scope but still present horrible consequences for transgressions.
These are films that are meant to inspire non-believers to convert and/or reinforce the beliefs of Christian viewers by showing the consequences of wrong actions and remind them of what will happen during the biblical apocalypse and/or after death.
Not to be confused with Christian genre films, which use genre (sci-fi/horror/fantasy) conventions to trick people into watching church stuff.
There are many, many films of this type not listed on Letterboxd. I'll try to add some and if anyone knows of any others that are listed on the site that I've somehow missed, please let me know in the comments! Thanks!
