This show by creator Anthony E. Zuiker describes the hard-working assignments carried out by the Las Vegas Police Department Crime Scene Investigations bureau , in the city of Las Vegas, Nevada . Being the second busiest crime lab in America , CSI investigators use the best scientific and technical methods to resolve enigmas and detain delinquents , utilizing complex analysis and the occasional leap in logic . Led by hard-nosed Captain Jim Brass (Paul Guilfoyle) and by Grissom (William Petersen , being subsequently replaced by Ted Danson and Larry Fishburne) , as his second in command , who while attached mainly to their works , they do make friendly connections with his staff . And at least one friend is willing to relocate entirely to work with quirky Grissom , Sara Sidle (Jorja Fox) . With an extreme dedication towards their quest for the true facts , he and his elite team of investigators work several twisted cases using scientific skills and equipment that are capable of finding valuable tracks from the most allegedly unlikely sources .
The Las Vegas PD Criminalistics Division follows essentially the nights of the detectives , pursuing perpetrators using scientific analysis and solving crimes that practically every other crime lab has given up on . As they record at all stages of the process of decomposition , local predation , and of course, bugs entomological interference . The choice to place this series in Las Vegas was not random , among US crime labs , Las Vegas is the second most active, surpassed only by the FBI lab at Quantico, Virginia . In addition , Grissom and Catherine are loosely based on real-life LVMPD criminalists . The extreme popularity of this TV series was credited for a large surge of applications for courses in forensic science . Some actors attended actual autopsies over the course of the series for personal research purposes . The majority of the techniques and technologies used in the CSI shows are accurate and true to reality , though the writers and crew readily admit that they "time cheat" ; tests that take seconds in the show often take days or even weeks in real life . This exciting series packs a moving atmosphere by means of shaky camera and reconstructions in a really dynamic style .
The nice actors who play these notorious characters are the followings : 1- CSI is led by Gil Grisson nicely performed by William Petersen , Gil has a long curriculum , at only 22, Grissom became the youngest country coroner in California history , he enjoys teaching , perhaps in part because it provides him with a structured social setting in which he can find success through sharing his interests . Grisson becomes emotionally involved in cases and often offers pointed quotations to illustrate his reaction . 2- Marg Helgenberger plays faithfully Catherine Willows , she became an exotic dancer . Finally finding her calling , she danced her way through a medical technology . Her supervisor, Grissom, mentions the fact that she was his first friend in Las Vegas, and the first person he recruited for his team . While a reliable and meticulous CSI , Catherine still enjoys flaunting her sexuality, and occasionally uses it to make a point or win over a difficult suspect , she is a single mother with an attitude and a complicated family life . 3- Sarah Sidle well played by Jorja Fox , CSI Sarah appears in the second episode of the series, called to run an internal investigation , she is ferociously intelligent and adept observer . Six years after she arrives from San Francisco, Grissom and Sara - who keep their relationship hidden- are finally shown to be a couple , as Gil reveals their relation during Sara's kidnapping , that she is the only one he has ever loved . She suffers depression due to her violent childhood and more recent ordeal . She leaves him to return to California to confront her ghosts , while Grissom , giving her the space she asks of him, throws himself entirely back into work . 4- Wisecracking , deadpan Jim Brass is nicely played by Paul Guylfoyle , he is an ex-New Jersey cop turned CSI turned cop again . He tries his best to be a good cop and a good man while attacking the underbelly of Las Vegas' seedier culture . While he still has an eye for the ladies , he is shown to live a solitary life , married to his job , and occasionally indulging in a heart-to-heart over single-malt with Grissom, or telling war stories to the CSI team . He is a particularly talented interrogator , moving between sincere sympathy and provoking angry , revealing outbursts from suspects . 5- Gary Dourdan plays rightly Warrick Brwon , he is a complex character, with idealism and compassion , humble despite his strong intellect and investigative talents, but with personal demons that threaten to wreck his life and damage the reputation of his team . Warrick has an addiction to gambling ; in addition to the financial and psychological problems gambling causes him , Warrick also runs afoul of the law on several occasions , though he is mentored and sometimes covered for by his supervisor , Gil Grissom . 6- George Eads acts as Nick Stokes , he is a solid , reliable worker and witness for the prosecution, but becomes driven to make a case stick when angered or appalled . Nick is generally considered the most low-maintenance of the crew , he represents the emotional heart of the series , being deeply empathic and does not hide his feelings , especially from the families of victims of crime ; he is a solid, reliable worker and witness for the prosecution . 7-David Berman, who plays assistant coroner David Phillips , is also a head researcher for the show .
