I'll Always Know What You Did Last Summer is a 2006 American direct-to-video slasher film. The film is the third installment of I Know What You Did Last Summer franchise, but does not have any of the cast returning from the first two installments, thus making it a standalone sequel to I Still Know What You Did Last Summer. The film instead takes the basic myth of the series with a new set of characters. I'll Always Know What You Did Last Summer was released on DVD on August 15, 2006.
