"The Avengers: Age of Ultron" official trailer has over 45 million views, but some of the fans may have missed an unknown character who may be of some significance in the movie. The trailer shows a woman standing with Chris Hemsworth, who plays Thor in the movie.

The trailer begins with James Spader's voice as Ultron, the main villain in the movie. The trailer goes on to show the superheroes and Ultron. 37 seconds into the trailer, the viewers get to see the superheroes all enjoying an evening out with drinks, but there is one additional unknown character standing next to Thor.

All the superheroes are dressed casually for the occasion, suggesting that it is more of a social gathering rather than a mission. Is the mystery woman Thor's date for the evening? Traditionally Thor's love interest has been a character called Jane Foster, played by Natalie Portman. Will "The Avengers: Age of Ultron" introduce a new love interest for the Asgardian?

The trailer also seems to introduce two new characters fighting alongside Ultron. The new characters look like Quicksilver and Scarlet Witch. The powers demonstrated by the two characters in the trailer are very similar to the powers of the "X-Men" characters.

The rivalry among the superhero team members is evident in the trailer. Tony Stark is seen taking on Hulk with his Hulkbuster suit and Thor is seen lifting Tony Stark by gripping his neck. The trailer also shows the villain telling the superheroes that they were all "puppets."

Rivalry among the superheroes is not new. Readers who have seen the first "Avengers" movie will remember the distrust the team members had and one of the scenes showed all of them arguing with each other. One interesting aspect to note from the movie is that Loki planned to unleash Hulk on the others.

Will the villain in "Avengers: Age of Ultron" succeed where Loki failed? Mark Ruffalo, who plays Hulk in the movie is seen fighting hard to control the monster within him. Will Tony Stark be able to subdue Hulk? Or will Natasha Romanoff use her intelligence to help Bruce Banner to calm down? Please share your opinions in the comments section below.
