One final fire work display brings an end to a brilliant night. So far, so good Rio, let's keep it going.
And here comes the flame! French Open winner Gustavo Kuerten brings it into the Maracana before handing it over to basketball player Hortência Marcari. She carries it up the stage to Vanderlei Cordeiro de Lima who lights the flame for Rio 2016.
There's time for one last samba show kicks off before the lighting the cauldron.
We are still going here. We've had the Olympic anthem, we've had the oaths, just need the torch lit.
The Olympic flag is now carried in by some of Brazil's sporting greats, including icon of women's football Marta.
BOOOOOOO. Temer's presence goes down as everyone expected. He declares the Games officially open as quickly as possible and we move on.
Brazil's interim president Michel Temer now has the mic. This ought to be good...
It's all very grandiose from Bach. "We are living in a world of selfishness," he lectures. It's difficult to listen to someone from the IOC harp on like this.
Bach says: "We live in a world of crisis, mistrust and uncertainty. Here is our Olympic answer. The 10,000 best athletes in the world competing with each other and at the same time living peacefully together, sharing their meals and emotions."
Thomas Bach has been speaking for AGES.
After all the athletes had made the way into the Maracana, the fireworks weren't bad.
Nuzman rescued that well and signs off in style before handing things over to IOC president Thomas Bach.
Uh oh. Nuzman's speech is going swimmingly until there is a reference to the Brazilian government. Boos quickly follow,
Nuzman says: "Brazil welcomes the world with open arms. I am the proudest man alive."
One more spectacular firework show erupts before President of the Rio 2016 committee Carlos Arthur Nuzman, a former volleyball Olympian, addresses the crowd.
That's it! Everyone is here.
And here comes Brazil! The Maracana is suddenly doused in green as 477 athletes home athletes dance their way out.
The team of 10 refugees gets an enormous cheer from those in attendance at the Maracana. You can read their stories here.
Jamaica were a huge hit when they walked out earlier, even if Usain Bolt wasn't in attendance.
Etimoni Timuani, the sole representative of Tuvalu, makes his way out. The 24-year-old is a footballer in the Tuvalu A-Division but he will run in the 100m qualifiers next week.
Tonga's Pita Taufatofua leads his country out and he has gone heavy on the oil. The taekwondo hopeful looks a bit more WWE this evening.
Serbia, led by Ivana Anđušić Maksimović, are out with Novak Djokovic in tow. He is another tennis superstar yet to taste Olympic success. After picking a bronze medal in 2008, he returned to London in 2012 where he was beaten in straight sets by Andy Murray in the semi-finals. With every other honour in professional tennis already won, can he add Olympic gold?
And here come... Russia. What will their reception be like? Not too bad, actually. There is a smattering of boos around the Maracana, but it's all faily ambivalent.
A beaming Rafael Nadal led Spain out earlier this evening.
