"You don’t have to have seen all the Marvel films to walk into Avengers 2 and have a good time," Marvel producer Jeremy Latcham said in his interview about Avengers: Age of Ultron. However, it never hurts to have a glance at the Avengers world before you go for the second movie in this series.
The Avengers
Iron Man, Captain America, Hulk, Thor, Black Widow and Hawkeye make up the original Avengers. And as you know, some of these heroes, namely, Iron Man, Captain America and Thor have their own movie franchise running. It is not surprising when the movie takes off from where Captain America: The Winter Soldier (2014) ends. 'The Twins' and Ultron are the newbies in the second Avengers movie which is hitting the screen after 3 years.

The Twins
The Twins Pietro and Wanda Maximoff - better known as Quicksilver and Scarlet Witch - make an appearance after the end credits in Captain America: The Winter Soldier. They are special and they have come out of a dark place. Quicksilver is the fastest hero you will see and he can put Usain Bolt to shame any day. The Scarlet Witch has telekinetic powers - including the ability manipulate her enemies. And, that's not all. They hold a grudge against Iron Man, and join forces with Ultron. A trip down the memory lane and back to action brings The Twins' story and the Avengers' story into the same frame.

Ultron
That brings us to Ultron. In the Marvel Universe, Ultron is created by Hank Pym, but in the movie Ultron is brought to life by Iron Man aka Tony Stark. Ultron is a sentient artificial intelligence and is hell bent on destroying the human race. Ultron keeps upgrading himself – and he can flit in and out of machines in microseconds, making him one of those villains who give heroes a tough challenge.

Vision
Vision is an android created by Ultron and it is Paul Bettany, who is JARVIS' voice, who gives it life. He has a back story and his story will pivot the series in the future. As for what we can expect from the Vision, Paul Bettany told Mirror: "He can change density. He can reach inside of you, grab your heart and pull it out. It's really cool."
Human touch
This time around, the director adds a bit of personal touch. There is a back story for almost every character and they are given ample time. And then there is the budding romance between Bruce Banner and the Black Widow.
The movie
International locales, metal on metal war, lots of jaw-dropping action - what is a superhero movie without all these, right? There are peppy one liners and then there are soul searching dialogues. There is a change of locales too. This time around they have gone outside the USA to shoot. South Africa, Seoul - watch the movie for more.
The question remains
When the first Avengers movie came out, they had rallied under the organisation called S.H.I.E.L.D. But S.H.I.E.L.D. was infiltrated in Captain America: The Winter Soldier. So who will lead our heroes? Will it be Tony Stark or Captain Steve Rogers? That is something to be found out by you.
