2 plot holes
Directed by: Peter Hyams
Starring: Jean-Claude Van Damme, Bruce McGill, Ron Silver, Mia Sara
Factual error: As Walker and Atwood are falling from the building in 1929 New York City, the reflection of Vancouver's Harbor Centre is visible in windows. Furthermore, the Harbor Centre was completed in 1977, so this is a double goof. (00:22:45)
McComb: When I'm in office it's going to be just like the 80's. The top 10% will get richer and the other 90% can emigrate to Mexico where they can get a better life.
Question: How can their house still be standing in 2004 when it was destroyed in 1994? Even if they rebuilt it it wouldn't look s old, it would only be a few years old.
Answer: In one of the flashbacks, it is shown that the wife designed the house and had been thinking about it for a long time. I think the easiest answer to this is: the house was simply rebuilt the same as it was.
Answer: My understanding was the timeline had been reset in such a way that the explosion had never happened.
Except that the explosion did happen. When Max carries Melissa out of the house to prevent her death again, their house is exploding in the background. This is because McComb had placed a bomb in the house to ensure that the explosion would kill Max which of course had ultimately failed.
The explosion happened, but it was before Max returned to his own time in the future. Once he went back through the time portal, everything somehow reset itself to before the bomb being detonated. The previous events in the past were erased in favor of an alternate timeline. The movie does not attempt to give a logical explanation, and it makes no sense, as most time-travel stories never do, but a "suspension of disbelief" is employed here. We're supposed to accept that it happened. Max is the only character who knows what the previous timeline was like, but he now has no idea of current events (like his wife and son being alive) in his alternate life during the intervening time from when he was in the past and returns to the "new" present.
Answer: The explosion did not happen because, by killing the younger McComb, Max prevented the timeline in which McComb planted the bomb. In the new timeline, Senator McComb mysteriously disappeared 10 years ago and was never heard from again.
