What is a Logline?

A logline (also called a "hook") is a one to two sentence description of your movie that captures the essence of the story in a way that makes people want to see it.

The Four Components of a Hook

Per WTFB methodology, every effective hook contains these four elements:

1. Characters

  • •Who are they?
  • •What do they want?
  • •What are their goals?

2. Conflict

  • •What is the main obstacle to achieving their goal?
  • •Who or what opposes them?

3. Setting

  • •Time period
  • •Genre
  • •Style/tone

4. Action

  • •What exciting things happen?
  • •Never be boring!

Logline Formula

code
[ADJECTIVE] [PROTAGONIST TYPE] must [GOAL/ACTION]
when [INCITING INCIDENT/CONFLICT],
or else [STAKES].

Alternative Formula

code
When [SETUP], a [PROTAGONIST] must [OBJECTIVE]
before [ANTAGONIST] [THREAT].

Genre-Specific Formula

code
A [GENRE] about [PROTAGONIST] who [SITUATION]
until [CATALYST] forces them to [ACTION]
against [ANTAGONIST/OBSTACLE].

Classic Logline Examples

Raiders of the Lost Ark

"An archeologist is hired by the U.S. government to find the Ark of the Covenant before the Nazis."

Breakdown:

  • •Character: Archeologist (implies adventure, intelligence)
  • •Conflict: Race against Nazis
  • •Setting: Implied WWII era, adventure genre
  • •Action: "Find" + competing with Nazis = excitement

Gladiator

"A Roman general is betrayed and his family killed by an insane emperor. Now a gladiator, he comes to Rome for revenge."

Breakdown:

  • •Character: Roman general (status, skill)
  • •Conflict: Betrayal, loss, revenge against emperor
  • •Setting: Roman era, epic drama
  • •Action: Gladiator combat, revenge journey

ANTAGONIST/OBSTACLE: ___________________________________
(Person, force, or circumstance opposing them)

STAKES: ___________________________________
(What happens if they fail?)

UNIQUE ELEMENT: ___________________________________
(What makes THIS story different?)

Step 2: Draft Loglines

___________________________________________________

Draft 2 (Add specificity):

code
___________________________________________________
___________________________________________________

Draft 3 (Add stakes):

code
