Fans of the Marvel Superheroes movie franchise's next offering, Avengers 2: "Age of Ultron" are eagerly anticipating its release which will be in May 2015.

The cast and crew are busily filming in several locations around the world. In this movie, the Vision will be introduced and fans will learn about the character's back story.

Fans' appetites are getting whetted with reveals coming from director Joss Whedon that there is a connection between J.A.R.V.I.S., Tony Stark's very smart AI, and the Vision. Paul Bettany is said to play the part of the Vision, IGN reports.

Of course the biggest issue concerning the filming of Avengers 2: "Age of Ultron" is Scarlett Johansson's pregnancy. According to Us Weekly, Johansson is due to give birth in August and they are still not done with the shooting.

There are many tricks that can be done to hide flaws and other unwanted things during and after filming. In the case of Avengers 2, it is Scarlett's growing baby bump. With her skintight costume, that seems impossible to conceal so the only sensible solution is to use body doubles.

According to Entertainment Weekly, director Joss Whedon revealed that they are using not just two, but three body doubles for Scarlett in order to do all the heavy stunts she has to do in the movie in her role as Black Widow. The body doubles will also be used for scenes where her growing tummy would otherwise be noticed. She will also be wearing some high-waisted outfits to hide the bump.

Whedon also said that they did not trim any of the scenes involving Scarlett. They were also given dots on their faces because Scarlett has a mole on her cheek. This will help Marvel during post-production as they can easily project Scarlett's face digitally on their bodies.
