Knives Out works well for learners who already understand English comfortably and want more challenging listening practice. With the dialogue moving at a natural rhythm, viewers should catch most of it, although a few moments may still be challenging. The language mixes everyday English with a few expressions that need attention, so it works best for learners who already have a solid base. The narrative adds extra difficulty because learners need to track events, motives, or character relationships. For learners around B2/C1, this can be a practical choice for building confidence with more complex narratives.
