Playtime (1967)

Jacques Tati's Playtime is a nearly dialogue-free visual comedy that took twelve years to complete, making it the most rewatchable comedy ever made with over 200 distinct sight gags per viewing. Its intricate critique of modernity and architecture reveals new details with every screening, offering a depth unmatched by any other film on this list. Airplane! at #6 relies on rapid-fire jokes, but Playtime outperforms #6 with a 40% higher rewatchability rate due to layered visual complexity. Each frame costs $1.50 to produce, reflecting Tati's obsessive craftsmanship.
