Brian Dennehy's Commanding Performance as Brig. Gen Leslie Groves drives this TV-Docudrama about "The Manhattan Project", the Scientific/Militaristic Collaboration to Design and Build the First Atomic Bomb.But Producing the "Super Weapon" opens up a "Pandora's Box" of Conflicting Philosophies and Strategic Questions that Human Beings were Forced to Answer, and Answer Quickly.History is Played Out quite Accurately, or as Accurate as something like a TV-Movie is Capable. It's an Astonishingly Detailed Account of the much Talked About Event."The Manhattan Project, Los Alamos, Oak Ridge, Trinity, Fat Man & Little Boy, Oppenheimer, Hiroshima, Nagasaki, Fall Out", and other Terms enters and remains in the Lexicon of Nervous Language to this Day. This is a good Dramatization. David Strathairn is Excellent as Robert J. Oppenheimer, "Oppie", to His Friends and Colleagues. He is more of a Complex Person than Groves and it wasn't as Easy to Flesh Out, but is given His Due and enough Screen Time to be a Fair Account of the Man.Overall, the Movie is a Must Watch for Historians and for Anyone Interested in War Room and Laboratory Intrigue where America's "Hawks and Doves" Mated and the "Love Child" and its Offspring are Still Alive and the Biography is Not Yet Complete.

TV Movie about the creation and use of the atomic bomb in World war II, that is impeccably well researched, detailed, inteligently made and graced by an All-Star collection of secondary actors.Unlike many north American movies and docs, Day One avoids patriotism (in fact it tilts against the use of the bomb) or the temptation of proposing Oppenheimer as a martir. Instead, Oppenheimer's real life ambiguity is represented perfectly. He doesn't want to betray a friend that was investigated for communism but he does it. He thinks about using the bomb as a demonstration at some point but turns into the opposite side: arguing that it may fail or give the Japanese a chance to prepare for an eventual attack. History will never fully understand the person that was Oppenheimer.Another key figure is Leslie Groves. He's a perfectly efficient militar who runs every possible detail of what happens in Los Alamos. He's the force behind the making of the bomb and he makes it sure that it will be used. Brian Dennehy portrays Groves' old fashioned strenght, intelligence and single-mindness perfectly.The third most important person here is Szilard, a physicist whose ideas were key for the development of the bomb but who turned against it's use against Japan (or any other nation) asking President Truman not to deploy the bomb over Japan. He's perfectly captured by Michael Tucker who even resembles the real Szilard. Szilard proposed a demonstration (deploy the bomb without killing anyone to show it's power) that was rejected.The movie poses the debate: Should the US of the time be accountable for the use of the bomb?I myself see arguments for both sides:On one hand, the atomic bomb had to happen. It was a natural conclussion of the ever inspiring scientific and physic discoveries at the start of last century. Also, throwing it as a demonstration would have indeed been risky if it failed. The Japanese military was scattered and divided at the time, and it's difficult to negotiate with a bubble of voices. Civilians (kids and women) are killed with other weapons too. They were in Dresden for example. The bomb ended the war.On the other hand the bomb had cost too much money not to use it. They wanted to know what was it's devastation power. They didn't try a serious effort to negotiate a surrender with Japan. They picked cities where the devastation could be bigger. The Japanese were weak at the time, they may have been defeated by other medium.The movie also offers some curiosities as Kyoto not being one of the bombed cities due to the fact that one military authoriy respected it's traditions and Arts too much and the division between the Navy wanting to give fair play to the Japanese (with at least some hours-long warning) and the Army just wanting to bomb the hell ouf it.

I am usually suspicious of docudramas, but from the books I have read and the documentaries I have seen on the topic of the making of the atomic bomb, I would say that this movie does not veer too far from the truth. There is very little of "certain events have been changed for dramatic effect." In reading histories you often get bogged down in details and do not have clear visual images of the people or environments, and documentaries usually try to piece together fragments of interviews and archival footage. I found that this movie was able to supply a coherent narrative while presenting the major players and events. No fancy cinematic effects, just straightforward story telling. It's a major undertaking to tell this story and this is a quality production.I thought the choice of actors was quite good. Brian Dennehy makes a good general Groves and Michael Tucker is almost a dead ringer for Leo Szilard. Of course there is only one Oppenheimer, but I thought David Strathairn does a good impersonation. They kind of went overboard on Einstein's hair, that wig must have weighed several pounds.It probably helps to have a little background on the topic before seeing this, since there are a lot of players. The whole effort had a cast of thousands, and this movie has a cast of several dozen. One thing I thought could have been better was an easier identification of the initial appearances of various people, maybe even subtitles. For example, Patrick Breen is listed as playing Richard Feynman, but I missed catching his appearance even though I was looking for him.I thought the movie was particularly good in presenting the back-room discussions about the decision to drop the bombs. That will be debated for all time I am sure, but you come away from this thinking that it was a mistake. In that you would be in agreement with Generals Eisenhower and Marshall as well as Truman's Chief of Staff Admiral Leahy. Were over 200,000 people sacrificed in order to make a statement to the Russians or to prevent their taking a part of Japan? How many U.S. lives were saved by the bombings? Once there was the bomb, was it inevitable that it be used? Could not a demonstration have been scheduled? And so on.For a complete history the book, "The Making of the Atomic Bomb," by Richard Rhodes is good. I found the 1981 documentary, "The Day After Trinity," to be excellent. It has archival footage, but most importantly it has interviews with many of the major players. I think this movie makes a sincere attempt to tell the story, within the limitations of a normal movie run-time, of one of the defining events in the history of mankind.

"Day One" feels like a portrait of the longest pre-meditated murder in the history of mankind. There are the killers, the unwitting accomplices, and the witnesses. It's all so well-documented, so perfectly arranged. This is the coldest kind of tale imaginable. Given the opportunity to put a distance of emotion and miles between the countless innocent dead and some perceived military victory, a country at large was deceived into believing that some great good or justice was being served.In spite of how you or I might see the results of the design, construction and eventual detonation of the first nuclear devices, this film doesn't take sides. Brian Dennehy and David Strathairn (two of my favorite actors) create incredibly believable characters. Michael Tucker, who looks very much like Leo Szilard, is excellent as well. I enjoyed Joseph Sargent's directorial work, a sort of off-hand realist quality he brings to nearly all his films. It serves the story well. "Day One" is a good film, just not the most engaging or tightly woven one. Your interest should depend directly on your familiarity with the subject matter.
