In just a little over two months, Marvel's biggest movie spectacle of the year is going to hit theaters. The much-awaited sequel to the superhero team movie "The Avengers" is near, which is just the perfect time for writer-director Joss Whedon to reveal his take on the characters. 

Empire interviewed Whedon back in April 2014 in the set of "The Avengers: Age of Ultron." However, some of the questions and answers were not included in the print edition. Now, the magazine has released the other part of the interview and it's just perfect timing. 

In the interview, Whedon talked about how Ultron is, as a villain, for him. He finds it interesting that the mechanoid is always angry and this is why he got James Spader to do the role. 

"I hired the smoothest talker in Hollywood to play him. I did it on purpose. I needed a guy who can give you the Morpheus but then can just LOSE HIS S***. Spader's really good at that and he's really good at finding the darkness, but also the comedy," Whedon said. 

The director also admitted that he had to change Ultron's powers because the antagonist is omnipotent in the comics. In the movie, he has a weakness and a need, which is necessary to make him into a deep character. 

"When Ultron speaks, he has a point ..." Whedon said. "And that he hates the Avengers for bringing him into this world, and he can't really articulate that or even understand how much he hates humanity." 

As for Quicksilver and Scarlet Witch, he believes that a backstory is unessential for these two Avengers because they are already raring to go. 

"Don't put in more, work with what you have," he said. 

This wasn't the case for Ultron. Whedon had to put more work in developing the character as the mighty villain.  

As for Hank Pym/ Ant-Man's absence, he explained that connecting the character to the story "was a bridge too far." Rather, he needed to make Ultron the brainchild of one of the Avengers, and Tony Stark is the best guy for it. Moreover, he pointed out that "Age of Ultron" isn't just about Stark's fault in making Ultron, it is also about the responsibility that comes after the creation. 

"The Avengers: Age of Ultron" hits theaters on May 1.
