Starting in 1997, Greuel worked in the film industry for five years at DreamWorks, where she worked beside director Steven Spielberg and Hollywood mavens Jeffrey Katzenberg and David Geffen.
Greuel was a studio liaison to the government sector and organized political fundraisers for the three founders of DreamWorks.
For his part in showbiz, Garcetti appeared in cameo roles in such productions as "All My Children" and even played a fictional mayor on television.
He also is a member of the Screen Actors Guild, he says.
Both candidates are touting those sensitivities to Hollywood as the entertainment industry in Los Angeles has been facing stiff competition from outside the state, enhanced by tax incentives or lower costs.
The Los Angeles job base thrives partly on Hollywood productions staying local.
Obama-Clinton Part II
California, a Democratic stronghold, was a major battleground between Barack Obama and Hillary Clinton in the 2008 Democratic presidential primary.
Villaraigosa put all his chips on Clinton and endorsed her. In this month's election on his successor, Villaraigosa isn't extending an endorsement, though he has lamented the recent negative turn in campaign ads.
Clinton won the California primary, but Obama went on to win the presidency.
Political observers are casting Greuel and Garcetti as modern-day proxies of that Clinton-Obama rivalry.
Greuel supported Clinton in the 2008 race. In fact, Greuel worked in the presidential administration of her husband former President Bill Clinton, who is endorsing her in this month's race.
Garcetti was one of five co-chairpersons for Obama's 2008 campaign in California.
Bill Clinton has been visible in his support of Greuel; Obama has refrained from weighing in on the race because the candidates are both Democrats.
Despite the two candidates' Democratic credentials, Garcetti is viewed as more conservative, if his support among conservative voters is any indication.
The USC/Los Angeles Times poll found Garcetti with a 21-point lead among conservative voters: He led Greuel 54% to 33%.
Curiously, he was leading her in other parts of the political spectrum, too, but with smaller margins: Garcetti was ahead 45 to 44 among moderates and 50 to 43 among liberals, the poll said.
In fact, Garcetti was leading Greuel on her home turf in the San Fernando Valley, 47% to 43%, the poll said.
The USC/Los Angeles Times survey reveals a quick change in fortunes for the two candidates.
A week before that poll, Greuel and Garcetti were in a virtual tie, according to the Edmund G. "Pat" Brown Institute of Public Affairs at California State University, Los Angeles.
The electorate gave the institute a vivid assessment of the two candidates.
"More voters say that Garcetti, by a slight margin, will be the better candidate in providing leadership and fighting crime, while voters prefer Greuel for handling education and as a candidate who 'cares about people like me,'" the institute said.
"The most cited negative by likely voters against Greuel is that she is too close to special interests and unions, and the most noted criticism of Garcetti is that he cannot be trusted," the institute added.
Among the biggest issues in the mayoral race is the role of unions and their campaign spending.
