Nell Minow Movie Mom Surprisingly biting film with great performances by Cynthia Nixon and John Lithgow Rated: 4/5 Aug 15, 2002 Full Review Roger Ebert Chicago Sun-Times A clever, funny and very skillful thriller about how the kid builds his own atomic bomb. Rated: 4/4 Jan 1, 2000 Full Review Richard Freedman Newhouse News Service Marshall Brickman's The Manhattan Project is also about the development of a nuclear device, but it's a lot of fun and perhaps the most exciting movie of the summer season so far.

Claudio C The Manhattan Project (1986) One of the Worst Movies From the 80’s (11,869 – 01 Aug 2025 – by Claudio Carvalho) Scientist John Mathewson (John Lithgow) and his team research a process to refine plutonium to almost 100%. He is transferred to a better laboratory in Ithaca and when he rents a house with the divorced real estate agent Elizabeth Stephens (Jill Eikenberry), he feels attracted to her. John meets her teenage son Paul Stephens (Christopher Collet) and invites him to visit his laboratory. Paul is a prankster and a brilliant student and decides to break into the laboratory later, with his girlfriend Jenny Anderman (Cynthia Nixon), to steal plutonium and build an atomic bomb to win the science fair. But his irresponsible act brings havoc to the town. “The Manhattan Project” (1986) is one of the worst movies from the 80’s. The flawed plot has a stupid scientist in the lead role performed by John Lithgow. The man brings a teenager to a classified facility to get into the pants of his mother. Paul Stephens is a irresponsible and reckless teenager, capable of breaking into a laboratory to rob plutonium. Then he exposes his mother, his girlfriend and other teenagers to the radiation and causing health risk to them to have a cancer. Laboratory security is a joke, allowing a teenager to handle the equipment. It is also impressive that there is no sniper capable of taking Paul down, especially because the teenager is unarmed and the bomb disassembled. The conclusion is ridiculous, with John Mathewson and Paul Stephens suffering no consequences for the acts. My vote is one (awful). Title (Brazil): “Jogos Fatais” (“Fatal Games”) My Blog: https://maniacosporfilme.wordpress.com/ Rated 0.5 out of 5 stars 08/01/25 Full Review Nick H This movie makes no sense but is a ton of fun. Great background noise, and nothing to be taken too seriously. I think I was shown this in a high school science class once, and that seems really wild looking back on it, LOL. Great cast. Rated 5 out of 5 stars 06/26/25 Full Review Francis V This is an excellent movie with an interesting plot. The acting is great and attention to details are very convincing. Rated 5 out of 5 stars 06/23/25 Full Review Michael B Not bad lite entertainment now that ai is here in 2025 we are in trouble if kids like this are around lol Rated 3 out of 5 stars 06/13/25 Full Review James R I've seen mostly negative reviews in this film, which I personally disagree with but respect everyone elses opinions. Maybe it's just my large interest in nuclear science, but I normally like these kinds of movies, like Wargames and stuff like that. I would suggest you go watch it to form your own opinion on it, but I still think it was entertaining, it makes you think a little, and yes, I know it's a silly premise, but it's still great in my eyes. I still think you should go watch it at least once. Rated 4.5 out of 5 stars 04/19/25 Full Review Rex J I cannot recommend this to anyone. The arrogance of the main character and the outright nonsensical ending left me hating this movie so much. I dont care who you are, you face repercussions if you steal nuclear material, which is what he did and he didn't face anything, just walks away!!!!!!!! Reality would have extremely different outcomes. I'm not suprised the director never made another movie, this is lefty activist claptrap nonsense at its zenith.
