Before the Olympics gets underway, you have to have an opening ceremony.
Some are amazing, some are not so amazing, but in recent years, all seem to be pretty expensive with the cost of putting on a show to remember.
The lights, the cameras, and well, the action, comes at a price for the host nation, but that's what it takes to put on a memorable show ahead of one of the most historic events in sport.

A lot of the time, people talk about, or remember, the opening and closing ceremonies more so than the actual Olympics itself.
Take the London 2012 ceremonies for example. Who didn't love seeing Rowan Atkinson back as Mr Bean or the Spice Girls having a reunion.
The costs of running the Olympics is huge, the cost of hosting an opening ceremony is just as huge. However, the Olympics is a special occasion and it needs a special opening ceremony to help kick start the event.
Here are the four most expensive opening ceremonies from summer Olympics'.
4) Sydney 2000 - Around £15m - Approximately £62,980 per minute
The first Olympics of the Millennium, and boy did Australia do it in style.
What started as a simple, yet, classy opening ceremony, turned into a showcase of epic proportions.
The performance was a mix of sporting history, as well as broadcasting the proud history of Australia as a country, and the culture from down under.
3) Athens 2004 - Around £26m - Approximately £110,000 per minute
Four years later, Athens spent roughly £11m more on their opening ceremony.
The main presentation for the Greek ceremony was demonstrating the differences between ancient Greece and modern Greece.
For the ancient side, there were large representations of Greek gods, whilst on the modern side, DJ Tiesto kept the party atmosphere going.
Another fantastic opening ceremony, but due to the cost of it, it's been blamed for their recent financial crisis.
2) London 2012 - Around £56m - Approximately £236,000 per minute
The second most expensive opening ceremony in Olympics history came back in 2012 when London, England put on quite a show.
England spent £30m more than third-placed Athens, and it was quite some spectacle. Travelling back in time and broadcasting the rich history of the country, as well as showcasing some of the national treasures throughout.
Largely deemed one of the best opening ceremonies in Olympics history, Danny Boyle did a great job highlighting British history and with 'The Queen' sky-diving into the stadium, it really was a night to remember.
1) Beijing 2008 - Around £75m - Approximately £314,000 per minute
As soon as it was announced that Beijing was going to host the Olympics, everyone in the world knew the opening ceremony would be massive and one of a kind.
The Bird's Nest was lit from the start to the finish and it was simply breathtaking on the eye. The light shows, the fireworks, and just everything else that came with it put Beijing in a league of their own.
The opening ceremony will go down in the memory of everyone. The performances from individuals throughout, the light shows that accompanied them, and the fireworks throughout demonstrated what you can do with a huge budget.
