Did You Know?


Stewart Rafill re-wrote the screenplay, so that a love story developed between the characters David (Michael Paré) and Alison (Nancy Allen). Rafill also removed a lot of scientific dialogue concerning explanations for the why and how of the time travel element of the film. See more »


When David and Allison are going to the ranch, there is vehicle at the end of the route. When the angle of the camera changes, the vehicle is far away and then close up. (It occurs at 1:02:40 and 1:03:00 in the movie). See more »


Allison Hayes: Why'd you join the Navy?

Excellent movie for a date
15 May 2006 | by See all my reviews

I first saw this film in a theater on a date, and it was an excellent choice, with science fiction for the guys, romance for the ladies, a pleasant feel throughout, and nothing too racy or too gory. I'm really surprised at all the negative comments about this film, and how it should be remade. I thought it was quite good as it was, other than in a few minor details, and I can't imagine it being remade without destroying the special moods it created.

My favorite part is the aerial scene of the orange groves and eucalyptus trees in inland California as David and Allison are driving down a rural highway, seeking out David's old friends. After all the tension in the earlier part of the film, this peaceful interlude set to pleasant music while soaring over the rolling hills is a beautiful contrast, and it becomes the high part of the film. The soothing old '40s music that David switches to on the car radio adds to the ambiance, and it becomes easy to imagine that time has stood still in this part of the country, which of course fits perfectly with the main plot. This mood is extended by David pointing out old landmarks he remembers: a church, a big old tree, and an old gas station. Then old black-and-white photographs on the wall of the gas station of David and his father bring the point home that David was telling the truth all along. It's a poignant scene as David is proud of his dad's accomplishments late in life while he simultaneously laments his father's passing. Too often nowadays films are made with "yang-on-yang" nonstop tension, action, and violence without any pleasant, relaxing high points, so I think this film was very well balanced in that way.

There are a number of other very well-done tidbits throughout the film. For example, David's question to the doctor, "Is this sort of thing possible now?", when describing time travel is something that only a bona-fide time traveler would say, and I remember the audience chuckled in delight at that perfect bit of dialog. Another gem is when David bluntly asks the transvestite in his jail cell, "What the hell are you dressed like that for?" I've known down-to-earth, practically-minded, heterosexual sailors, and that's exactly how they react to our modern era's confusing gender bending. Another gem was David flatly declaring that the water his friend Jim sees in the distance is a mirage, and then Jim ribbing David about David's mistake as they trudge through miles of water.

I thought the romance worked extremely well. Note David's defensiveness about his love life when he's in the '40s, and how standoffish his '40s girlfriend is, and then contrast that to the magnanimous personality of Allison in the '80s, who coincidentally has the same curly red hair as his '40s girlfriend--evidently the look David likes. Allison becomes the ideal version of his '40s girlfriend, and understandably becomes David's new focus in life. They make a very nice couple, I think.

There are admittedly some weak points in the film. The 2001-type vortex travel scene has some unconvincing effects, but considering they're trying to show what the fourth dimension looks like, which presumably has nothing in common with our universe, it's hard to find fault in their visualization. The glowing hands and electric arcs flying out from the arcade games and power lines are a little weak, as are people's reactions to those, and the carrying of top secret papers, and the implausible landing on a ship in a vortex, but I regard those are minor points. The modern day reaction of Jim to his old friend seems unrealistic at first until you think about it, and the explanation given about Jim's psychological problems after the experiment makes perfect sense and adds a bit of unexpected realism. In real life you can't expect to look up old friends and have everything go back to the way it used to be. Such details in the film fit together quite well, I believe.

Whether or not this movie follows the historical facts and rumors of the original Philadelphia Experiment isn't particularly important to me. What I care about is whether the film stands on its own as a piece of art, and in my opinion it definitely does. This is a film I find myself thinking about from time to time, and I like to watch it every so often. To me it's a film worth owning.
