本剧被称为中国版《急诊室的故事》。由《重案六组》原班人马出演，这一次警察们都变成了医生。而女主角王茜日前在接受记者采访时表示，因为在医院看多了生死，她都打算息影了。
《无限生机》的导演是近年来一直创电视剧高收视率的着名导演徐庆东，他继续起用《重案六组》、《一双绣花鞋》等电视剧的班底。《重案六组》中英姿飒爽的女警察王茜这次变成了精明乾练的苏大夫。昨天王茜接受记者的采访，她告诉记者，这次《无限生机》拍得非常不容易。剧组在开机前数月，由导演带队，主要演员以及其他主创人员到北京120急救中心、友谊医院、朝阳医院等现场实习，数十人跟随救护车抢救病人，观摩医院的大型急救手术和救治过程。体验生活期间，王茜每天就在医院急诊室值夜班，“每次夜里来了一堆病人，值班的医生人手不够了，我就真的上。”王茜说，她在实习期间，帮脑袋被砍伤的病人剃过头，给病人止血，推着上年纪的气憋的病人冲向救护室，美国《急诊室的故事》里的情节她全都赶上了。所以到拍戏现场，有一个工作人员突然晕倒，其他人都乱的时候，王茜上前“诊断”，真的叁下五下给人治好了。
《无限生机》从去年10月开始拍摄，剧组专门在通州搭了一座完备的医院，所有的科室、设备齐全。王茜说，故事的风格和《重案六组》有点相似，每集7个病例，围绕至少叁个重病人、四个以上轻病人的不同急救故事交错展开。拍摄难度最大的有两点，一个是天气，因为拍摄地没暖气，北京今年最冷的几天他们全都是在医院里过的，演员冻得直哭，发誓再也不拍戏了，二是一些专业的抢救过程，因为导演对这些要求非常严格，每一场戏都要让急诊专家看看，结果总是因为一些细节没做到位，整场戏不得不重拍。就这样，一部戏拍了4个半月。也因为这次拍戏，王茜说自己很疲惫，在医院实习看多了生死，都打算息影半年。
王茜说，这部戏她最大的一个体会就是大家都应该学点“急救知识”，“其实可能你只要学个两叁天，在关键的时候就能起到很大的作用，你小小的一个动作就可能决定别人的生死，尤其家里有老人的年轻人更应该学点。”下面一段时间，王茜给自己放假，要好好学习外语。

Recipient of the 2007 Golden Globe Award for Best Drama Television Series and multiple Emmy nominations, including Outstanding Drama Series for the past two years, "Grey's Anatomy" returns to the ABC Television Network for its fifth season.
Is "happily ever after" possible for Meredith Grey and Derek "McDreamy" Shepherd? With Meredith experiencing a breakthrough in therapy - the realization that she and Derek can be extraordinary together, rather than ordinary apart -- she and Derek now face the highs and lows of being a committed couple.
Continuing their first year as residents at Seattle Grace Hospital, Meredith, Cristina Yang, Izzie Stevens and Alex Karev have interns of their own to mentor, including Meredith's half-sister, Lexie Grey. Lexie has become a roommate and confidante to George O'Malley, who, after divorce with Callie, a breakup with Izzie, and learning that he failed his residency test by only one point, is striving to get both his professional and personal life back on track.
After attending to his girlfriend Rebecca's mental illness on his own, and revealing that he had gone through this with his own mother, Alex finds solace in Izzie's arms. Alex must continue through this difficult time, whether or not Izzie remains by his side.
Cristina, having finally won out over her tough-as-nails mentor, Erica, is back on track as a surgeon - but is there a chance for new love in her life as well?
With the encouragement of Mark "McSteamy" Sloan, Dr. Callie Torres has taken a chance on love with cardiothoracic surgeon, Erica Hahn; now, she and Erica must figure out what happens after the first kiss.
Overseeing the residents is the no-nonsense Chief Resident, Miranda Bailey. Facing marital troubles and the difficulty of balancing her work and personal life, Bailey has handed her responsibilities as head of the free clinic over to Izzie. Also striving for balance is Chief of Surgery, Richard Webber, who has reunited with his estranged wife, Adele.
The doctors of Seattle Grace Hospital deal with life-or-death consequences on a daily basis - it's in one another that they find comfort, friendship and love. Together they're discovering that neither medicine nor relationships can be defined in black and white. Real life only comes in shades of grey.
"Grey's Anatomy" stars Ellen Pompeo as Meredith Grey, Patrick Dempsey as Derek Shepherd, Sandra Oh as Cristina Yang, Katherine Heigl as Isobel "Izzie" Stevens, Justin Chambers as Alex Karev, T.R. Knight as George O'Malley, Chandra Wilson as Miranda Bailey, James Pickens, Jr. as Richard Webber, Sara Ramirez as Callie Torres, Eric Dane as Mark Sloan, Chyler Leigh as Lexie Grey, and Brooke Smith as Erica Hahn.
