(CNN) -- Ready or not, Russia kicks off the opening ceremony on Friday as the world turns its attention to Sochi for the costliest Olympic Games in history.
Spectators from all over the world will watch the lavish event and introduction of athletes, marking the official start of the Winter Olympics.
It is expected to feature a light show and music, with organizers hoping the fireworks are restricted to the sky -- and not to the Games whose preparation reports have been anything but dazzling.
After anxiety about terror strikes, controversy over gay rights and ridicule over poor preparations, the nation's officials have maintained that the sites in Sochi are secure.
Sochi will be "the safest place on Earth during the Olympics," said Dmitry Chernyshenko, head of the Games.
Russian President Vladimir Putin, who pushed the International Olympic Committee to hold the Games in the nation, will attend the ceremony.
"The head of state is expected to declare the Games open during the ceremony," said Konstantin Ernst, the main creative producer of the ceremony. "It is a requirement. And naturally Mr. Putin will be doing just that."
The ceremony, the only event scheduled for the day, is scheduled to last about two and a half hours.
"We believe this is going to be a respectable format. It will be very comfortable for the spectators," he said.
Some 40,000 people will be watching from the stands at Fisht Olympic Stadium in Sochi. And there will be classical music, lots of it.
Russian classical music star Anna Netrebko will perform the Olympic anthem at the opening ceremony, Ernst said.
"Most of the ceremony focuses heavily on Russian classical music," Ernst said. "Unfortunately, unlike London we cannot boast a plethora of famous world-known pop performers. This is why we are now focusing on what Russia is best known for musically around the world, namely classical music, but of course we have had several generations of popular Russian performers.
A day before, high excitement marked qualification events in the men's and women's slopestyle, women's moguls and team figure skating.
There's no doubt it's the issue at the forefront of people's minds.
Russia has drafted some 37,000 police and security officers to handle security in Sochi. But that's not been enough to assuage everyone's fears.
Toothpaste terror: A day after the United States warned of how explosive materials could be concealed in toothpaste or cosmetic tubes, its government Thursday temporarily banned all liquids, gels, aerosols and powders in carry-on luggage on flights between the United States and Russia.
A law enforcement source told CNN the effort is intended as a very targeted response to the threat that became public Wednesday, and should have a minimal impact on the traveling public. The Transportation Security Administration ordered airlines to ban the items from carry-on bags, but allow them in checked bags.
U.S. partnership: Meanwhile, U.S. authorities are working with the Russians and other countries to try to disrupt several possible threats, including the toothpaste tube concern, a U.S. intelligence source said Thursday.
The threats vary in credibility, and the biggest one traces to the group Imarat Kavkaz in Russia, which has publicly said its followers will try to disrupt the Games, the official said.
"The threat stream is credible, I think it's real," said Sen. Dianne Feinstein, D-California.
Private protection: The U.S. ski and snowboarding team has hired a private security firm, Global Rescue, to provide protection. It's not clear how much the firm could do in the event of a major incident, when Russian forces will be in charge. But it has been gathering intelligence on the ground and will provide an extra layer of protection as athletes travel around.
Ships for safety: Meanwhile, two U.S. Navy ships have steamed into the Black Sea, where they will be ready to help if any mass evacuation of U.S. citizens is needed. U.S. security officials have also been working with their Russian counterparts on how to keep the Games safe against the backdrop of a regional separatist movement that has used terrorism in the past and has threatened to use it during Sochi's Olympic Games.
Targets of threats: Americans are not the only ones who are jittery. Austria said this week that two of its female athletes had been the target of specific threats. Austrian media reported an anonymous letter was sent warning Alpine skier Bernadette Schild and skeleton racer Janine Flock they could be kidnapped.
We've heard it before: It's not the first time security issues have dominated the build-up to the Olympics -- Britain parked missile batteries on apartment block roofs and a warship on the River Thames before the 2012 Games. The Salt Lake City Winter Olympics in 2002 were held amid heightened security only months after the 9/11 terror attacks in
the United States -- and the 1996 Summer Games in Atlanta were subject to a terror attack.
When Russia bid to host its first Winter Olympics in 2007, a document quoted an expected cost of around $12 billion. That figure has ballooned to around $50 billion. That's more than four times over budget and surpasses Beijing's 2008 Summer Games -- making it the most expensive Olympics ever, summer or winter.
Russia had less than seven years to transform what was a fairly low-key seaside resort town into a Winter Olympics venue. The project required staggering feats of engineering in building a new freeway and rail link up a mountain, and a ski resort on the top. And yet questions over Sochi's readiness have dogged the final run-up to the Games.
Not quite there: While the sports facilities were completed in good time, journalists and others arrived in Sochi this week to find that some of the 40,000 new hotel rooms were far from ready and that construction workers were still hard at work on parts of the Olympic Park.
Thanks to pictures of chaotic scenes posted on Twitter, Russia's pride has not been spared.
But CNN's Ben Wyatt in Sochi reports that the picture is not all bad. His hotel has been "superb" and staff and Games volunteers are clearly making an effort to be helpful and speak English, he said.
While some media hotels and landscaping projects have not been completed on time, the sporting venues are all looking in very good condition, he said.
It'll be A-OK: The Games are President Vladimir Putin's pet project -- so the pressure is on for the Russian organizers to deliver and foster the country's reputation as a wealthy, modern state.
Every Olympics has protests. But thanks to social media, Russia is facing a global backlash.
What got many people riled was Russian lawmakers' passage last summer of legislation known as the anti-gay propaganda bill. The law makes it illegal to tell children about gay equality.
Open letter: More than 200 writers from around the world signed an open letter published Thursday in the UK newspaper The Guardian, calling for a repeal of laws that have placed a "chokehold" on the right to free expression in Russia.
"As writers and artists, we cannot stand quietly by as we watch our fellow writers and journalists pressed into silence or risking prosecution and often drastic punishment for the mere act of communicating their thoughts," the letter said. Authors Salman Rushdie, Jonathan Franzen and Nobel laureates Gunter Grass and Orhan Pamuk are among the signatories.
First athlete to protest?: Russian state-run media agency RIA Novosti reported that Russian athlete Alexei Sobolev sported an image on his snowboard resembling "a female figure in a balaclava wielding a knife."
That image purports to resemble members of Pussy Riot because the anti-Putin, all-female band perform while wearing balaclavas, headgear that shows only part of the face, the news agency reported.
Three band members were sentenced to prison for performing a song critical of Putin in one of the Russian Orthodox Church's most important cathedrals in February 2012. Band supporters say the musicians were political prisoners.
Designated site: There is a designated protest site in Sochi. But there's been criticism of organizers' decision to tuck it away in a hard-to-reach village seven miles from the main Olympic Park.
More protests may be yet to come -- perhaps even by athletes despite an Olympic Charter rule that states: "No kind of demonstration or political, religious or racial propaganda is permitted in any Olympic sites, venues or other areas."
