This film is a remake of the 1965 William Castle classic of the same title. It was made for TV, although that's not such a big problem on paper as the plot is very simple and there's not a lot of room for bloodshed anyway. The film also features a distinctly eighties style, which firmly puts the story in the time in which the film was made. Unfortunately, however, the focus of the film is spread thinly over a lot of different areas and as a result; the central plot suffers as its not fleshed out very well and the characters suffer too as we never really get to know anything about them. The plot focuses on two kids babysitting a younger one. They're bored and decide to get some kicks by making prank phone calls. The game soon gets round to "I know what you did", which involves phoning someone and simply saying that phrase. Unfortunately, however, they decide to call a Mr Adrian Lancer, a disturbed man that happens to have just murdered his wife...

The original film featured the same basic plot, so to call this one unlikely and the original not would be unfair. However, the fact that the original is so much better handled means that this version really struggles to get the plot across. The big coincidence of the girls' game and the murder isn't glossed over with any kind of gimmick which makes it stand out like a sore thumb. Furthermore, the girls themselves have very little character and Robert Carradine looks bored in his role as the murderer and so doesn't bring forward any tension or suspense. The plot is played rather straight for most of the film, which means things rather just drone on and it gets tiresome quickly. Tammy Lauren stands out in her role, though that's only because of her awful eighties haircut, while Shawnee Smith is mostly incognito. It soon becomes clear that the film isn't going to present any surprises and indeed the ending is rather typical. We do finish off with a final twist that is both nonsensical and redundant. Overall, I highly recommend giving the original a look if you want a fun lightweight thriller; but don't bother tracking this version down.
