Frequency is a very entertaining yet totally unbelievable movie, the plot of which revolves around solar flares affecting radio waves and allowing a sort of time-travel for a particular ham-radio operator. Still with me? Good, because apart from the silly science, this is a really good sci-fi/adventure/drama movie. Suspenseful and well-acted, the movie is high on production values and details.
Dennis Quaid stars as the fireman father, James Caviezel is the cop son, and Elizabeth Mitchell is the wife/mother. Through the time-travel setup, the son is able to communicate with his dead father via his dad's old ham-radio. Together, they try to avert the accident that leads to the father's death in a warehouse fire. Another bad-guy character crosses from the past reality to the present reality.
I'm not going to spoil the movie with particulars or more details.
The DVD has 2 good, informative commentaries. One is by director Gregory Hoblit, and one by actor Noah Emmerich and writer/producer Toby Emmerich. In Hoblit's, he reveals the ending he would have rather used. Although the movie ending was acceptable, Hoblit's idea would have been better from a logic viewpoint.
Deleted scenes, a documentary about the "science" in the movie, and a few other goodies at a resonable price make this a highly recomended DVD. Over!
