Take Down (1979 film)

Ed Branish, a snooty English teacher who finds his situation at Mingo Junction High School far beneath him and barely tolerable, flaunts his air of superiority over all, including his supportive wife, by frequently spouting platitudes from literary masters to validate his often contemptuous viewpoint.

No one realizes Nick's been filling in for his alcoholic father at a steel mill hauling I-beams when his dad's too drunk or hung over to show up, which is all too often.

Nick is kept busy at night fishing his embittered father out of bars and carried home across town, since they don't have a working car.

Nick hopes he can make up the missed school work in Ed's class to graduate in Spring but instead gets a tongue-lashing on how he should be held back as an example of the consequences of laziness and irresponsibility.

In turn, Nick calls Ed an "egotistical snob", telling him that he is more interested in proving how book smart he is instead of teaching and that he is clueless when it comes to the real world and its everyday problems.
