Leave your thoughts about I Saw What You Did.
| Creative LoafingMatt BrunsonCastle frequently employed gimmicks to promote his movies -- "Percepto" for The Tingler, "Emergo" for House on Haunted Hill, etc. -- but with this nifty thriller, the closest thing to a gimmick is the ingenious plot itself. |
| User ReviewWendy Si really liked this movie and im tryiing to find it to buy i want this one oh yeh |
| User ReviewLaDonna MYeah. I saw you. Not last summer. Maybe yesterday. Who knows? But anyways I know you did something. Which will lead me to get revenge. Even if it has nothing to do with me. |
| User ReviewMicah preally good movie not really scary, sort of sad a couple of girls make a prank cal and it goes terribly wrong when they visit his house (he just killed his wife) |
| User ReviewAngee 1I saw wat u did in last****************************** |
| User ReviewKatie Sthoroughly entertaining thriller. its not scary or violent even. its just really entertaining. i could not take my eyes off the girl who played Libby. I just enjoyed this so much. So so much. |
| User ReviewVita VIt is nothing like a good old classic. A must see movie. It will keep you in suspence. Watch it and tell me what you think. |
| User ReviewPrivate UJoan Crawford's giant wig makes it worth a watch! |
| User ReviewTrent MA fun to watch thriller-lite from Castle that sometimes borders on black comedy. The only standard Castle gimmick here is the prologue mentioned in the synopsis. |
| User ReviewWayne D...and I know who you are. I want to give it more than 3 stars, and I love the dark 60's suburbia in it, but it's not as great as the Tingler, House on Haunted Hill or Homicidal.Two girls play phone pranks and end up in a whole mess'a trouble. The concept has been redone since then of course (I Know What You Did Last Summer etc...) but this stands a a good time capsule and fun Saturday night (and pretty gentle) 60's thriller. |
