What do you call a movie about a broken elevator?

This joke plays a clever double game with the phrase "lets you down." The initial punchline suggests a movie about a broken elevator would be uplifting because it "never lets you down," implying it's consistently good or inspiring. However, the humor then pivots on the literal meaning of an elevator's function: to transport people up and down. A broken elevator, by definition, *fails* to let you down, or indeed, move you at all, leaving you stranded. The "actually, that's the problem" brilliantly snaps the joke back to the frustrating reality of a malfunctioning lift.

The comedic twist relies on this misdirection (Review), first offering a positive interpretation of "not letting you down" in the emotional sense, only to immediately correct it with the physical, inconvenient truth of an elevator that's stuck. It's a classic example of wordplay combined with a touch of situational irony, where the expected outcome (being lowered by an elevator) is precisely what's *not* happening, much to the chagrin of anyone trapped inside. This kind of humor often pokes fun at everyday frustrations by highlighting the absurdity of language when applied literally to a common predicament.
