"Intruders" is in my opinion the most underrated masterpiece when it comes to the topic of UFOs, alien abduction etc.... I gave this movie a well deserved 10!Of course, a lot of mistakes where made in the movie which you can clearly see, but no other movie has ever come this close to put down a realistic feel concerning alien abduction.The special effects used in the movie are stunning for it's time and for it's budget.I rediscovered this movie after 20 years, and as a kid, this movie truly got to me, and 20 years later it still does."ET" or "Close encounters" never had that effect on me.

I remember seeing this movie on VHS rental and I immediately liked it. It started me on reading Bud Hopkins' books on alien abduction. As stated here time and again, the acting is very good and the story very involving. I remember especially enjoying reading the book after viewing the movie. This way I had a visual reminder every time when reading. On all accounts Intruders is a convincing and scary movie that should please all lovers of the genre. @dunneboy from Sweden: I'm not sure which version DVD you got, but the movie's listed run time is 163 min. The R2 DVD of Intruders runs for 162 min.(And that's without factoring in PAL speedup:-)

This is by far the scariest and most realistic alien movie ever. This is the only alien movie to deal with aliens implanting a fetus in a human and showing hybrid alien and humans. This movie is based on the book "Intruders" in which Budd Hopkins uses hypnosis to reveal the blocked memories of alien abduction. You must see this movie.

Intruders, an over-long made for television movie, ranks as my third favorite film made on the topic of ufo's and alien abduction. Only Communion and The Interrupted Journey ranks ahead of it.Richard Crenna, the film's protagonist, is a therapist who must deal with the reality of ufo's when one of his patients thrusts an "alien abduction" account onto his plate. His initial reaction is to brush her off as a nutcase. Soon, when other people with similar accounts journey into his life, he begins to take a serious look at the possibility of ufo's actually abducting people.His investigation begins to uncover a certain amount of evidence and a government involvement(pre-X-Files) that forces him to take a 180 degree turn in his feelings about the subject.Richard Crenna, as pointed out by another commenter, does seem to be a composite of artist and author Budd Hopkins and Harvard professor John Mack. Crenna is very good in his role. I especially enjoyed watching his characters transition from non-believer into believer. The film is frightening in its depictions of abductions and encounters with aliens. There are several sequences featuring abductions and several scenes on board ufo's. Where Fire In The Sky seemed to tease the audience, Intruders wants to bombard it.Very, very frightening! A must see!
