An interesting concept that works rather well. This film may have worked as a theatrical release because it is one of the better TV movies I have witnessed.
Christopher Reeve was well chosen to play the provoking and thoughtless Sean Farrell, who will stop at nothing to determine whether or not Megan Lambert is his long-lost wife. Reeve certainly portrays well a dark and perhaps mad character in a role very different to Superman.
The wonderful Charlie's Angel Jaclyn Smith is a pleasure to watch (as always), and certainly proved her worth as an actress taking on a quite demanding role.
When viewing Nightmare in the Daylight, a lot of questions enter your mind - why didn't Megan do a particular thing; is Sean simply out of control or is he actually on the right track? Great twists and turns throughout certainly raises the suspense in a TV movie that proves small screen drama/thrillers do actually work. TV movies are not always the badly prepared and melodramatic humdrum that some people believe they are. 7/10
