Having previously watched this taped on VHS from an independent station in Jacksonville, FL, during the '90s, I felt the need to watch this again after the passing of one of the stars: Alan Arkin. In only his second starring role, he's quite effective as the malevolent Harry Roat looking for a doll filled with heroin. The woman who took it gave it to a man she just met at an airport. That man's wife is played by Audrey Hepburn playing someone who's blind. Her hubby leaves her alone in her apartment while he's out on assignment. Oh, and Roat has a couple of assistants he manages to convince to play his game. There's also a young girl who helps Suzy (Ms. Hepburn's character) along the way. I'll stop there and just say this is one of the most effective thrillers I've ever seen and my mom-who hadn't seen this before-agrees with me. Ms. Hepburn deserved her Oscar nom and when Arkin was asked why he didn't get his, he basically said one wouldn't get one for terrorizing someone as iconically beloved as her! Those last 8 minutes really pack a wallop, that's for sure! And Henry Mancini's score is one of his best. Ditto Terence Young's direction. I think I said enough so on that note, Wait Until Dark is highly recommended.
