百年50部英文燒腦電影賞析:[37]Source Code 源代碼

Army helicopter pilot, Captain Colter Stevens（Jake Gyllenhaal）, last aware of being on a mission in Afghanistan, wakes up on a commuter train traveling to Chicago. He finds that to the world around him — including his traveling partner Christina Warren（Michelle Monaghan）and the bathroom mirror ——he appears to be Sean Fentress, a school teacher. As he comes to grips with this revelation, the train car explodes, killing everyone aboard. Stevens regains consciousness inside an unfamiliar cockpit. Through a screen, Air Force Captain Colleen Goodwin（Vera Farmiga）verifies Stevens's identity. She explains Stevens is in the “Source Code”，an experimental device created by scientist Dr. Rutledge（Jeffrey Wright）. The Code allows its user to experience the last eight minutes of another compatible person's life within an alternate timeline. Stevens's mission is to use Source Code to discover the location of a bomb aboard the train and identify the bomber who detonated it. Goodwin explains that the train explosion occurred that morning, and was a warning by the bomber as a precursor to a larger dirty bomb that will be detonated in downtown Chicago. Stevens is unwillingly sent back into the Source Code to try again.
Stevens is sent back into the Source Code several times, trying different approaches each time including trying to warn the authorities on the train and trying to flee with Christina. None of these attempts are successful and in each case he is returned to the Source Code to try again. During one of Stevens' attempts, he learns that the train explosion occurred two months after an incident in Afghanistan which reportedly killed him. Once he discovers this, he demands more information from Goodwin. She explains that the remains of his body are in fact on life-support at the Source Code facility while his mind is hooked up to a computer system, the cockpit being a mental projection of his own mind to cope with the experience. Angered to discover this, Stevens requests that his life support be terminated after the mission is completed, to which Dr. Rutledge agrees.
Stevens eventually identifies both the bomber, a young man, Derek Frost（Michael Arden）, and the rented white van that he will use to carry the bomb into the center of Chicago. On his return, Stevens' information is successfully used by the military to capture Frost before he can trigger the bomb. Stevens is praised as a hero, but in private，Rutledge tells Goodwin to renege on the deal, and instead to wipe Stevens's memory so he can be used the next time there is such an incident. Stevens learns that the promise to him has been violated, and convinces Goodwin to let him return to Source Code once more, after which she will disable his life support, against Rutledge's orders.
Once back aboard the train, Stevens disarms the bomb, subdues Frost, and handcuffs him to a railing. Stevens calls the authorities to identify Frost and inform them of the location of the dirty bomb. He then calls his estranged father under the guise of a fellow soldier, mending the emotional distance between them. He challenges an embittered comic（Russell Peters）to perform a stand-up routine on the train, causing laughter throughout the entire train car, and then takes Christina aside. Asking her what she would do if she knew that she only had seconds left to live, Stevens begins to kiss her as his last seconds run out. As promised, at this exact moment, Goodwin disables his life-support and the scene reveals Ns actual, physical body as severely mutilated and comatose. Time freezes, but Stevens is surprised to find himself finishing the kiss, still aboard the train with Christina. He realizes that he will remain in the alternate timeline of the un-bombed train. The train arrives safely in Chicago, and he and Christina walk together and discuss their future.
Later that morning, Goodwin arrives for work at Nellis Air Force Base and receives a text that Stevens had sent earlier, just as news breaks of the failed bombing attempt in Chicago. The text explains that the Source Code effectively allows the user to change history within alternate timelines. Stevens' text ends with him proposing to Goodwin that when his alternate self in this timeline is used in a future Source Code mission, Goodwin should help him, and tell him that “everything is gonna be okay”.
陸軍直升機飛行員，柯爾特·斯蒂文斯上尉（杰克·吉倫哈爾飾）最后的意識是在阿富汗執(zhí)行任務(wù)，他在駛向芝加哥的通勤火車上驚醒，從他周圍的世界——包括他的旅行伙伴克里斯蒂娜·沃倫（米歇爾·莫娜漢飾）和浴室里的鏡子——他發(fā)現(xiàn)自己成了肖恩·芬特雷斯，一名中學(xué)老師。當(dāng)他面對這些出乎意料的事時，車廂發(fā)生了爆炸，車上的人全部死去。

再次返回到列車上，斯蒂文斯拆除了炸彈，制伏了弗洛斯特，把他的手銬到了一個欄桿上。斯蒂文斯通知當(dāng)局驗明弗洛斯特的身份，并告知他們安裝炸彈的位置。然后他以一個士兵為幌子，給與他疏遠的父親打電話，修補他們之間的情感距離。他在火車上站立不動表演，挑戰(zhàn)一個苦怨的滑稽演員（羅素·彼得斯飾），引發(fā)了整個車廂的笑聲，然后把克里斯蒂娜帶到一旁。問她，如果她知道她的生命只剩下最后幾秒，她會做什么，在最后幾秒將要用盡時，斯蒂文斯開始吻她。像承諾的那樣，在這一刻，古德溫停止提供對他生命的支持，場景轉(zhuǎn)換到他真實的嚴(yán)重殘缺的昏迷過去的身體。時光凝結(jié)，斯蒂文斯驚訝地發(fā)現(xiàn)自己親吻完畢，仍然和克里斯蒂娜在火車上。他意識到他仍在穿越的時光中，身處沒有爆炸的列車上?；疖嚢踩竭_芝加哥，他和克里斯蒂娜走在一起，討論他們的未來。
當(dāng)天上午的晚些時候，古德溫來到內(nèi)利斯空軍基地工作。就在新聞披露企圖制造芝加哥爆炸案失敗的消息時，她收到了斯蒂文斯早先發(fā)來的短信。短信說明源代碼能有效允許用戶改變穿越的時光內(nèi)的歷史。斯蒂文斯給古德溫的短信的最后，是給她的建議，當(dāng)他所對應(yīng)的那個自己在穿越的時間內(nèi)被用于執(zhí)行未來的源代碼任務(wù)時，古德溫應(yīng)該幫助他，并告訴他，“一切都會好起來的”。
