I was just calling out a clickbait, didn't know that is a crime. I went back and checked the definition of "irony". This does not match any of the three:

  * the expression of one's meaning by using language that normally signifies the opposite, typically for humorous or emphatic effect.
  * a state of affairs or an event that seems deliberately contrary to what one expects and is often wryly amusing as a result.
  * a literary technique, originally used in Greek tragedy, by which the full significance of a character's words or actions is clear to the audience or reader although unknown to the character.

It's situational irony, #2 in your list, since you'd expect people working on a film about corruption to be at least reasonably honest.
