While it is the first time for Sandra Bullock, the actress hailed as America's sweetheart, to play the role of the evil villain in a film, the Academy Award winner seems to be more excited over her son's reaction when he watches "Minions," according to Daily Record.

Taking on the role of Scarlett Overkill, Bullock admits that the part definitely allowed her to get out of her comfort zone not only in terms of the type of character she portrays but also the means by which the production was done. When asked why she agreed to play the villain in the animated film, the question appeared to be a no-brainer for the actress as she quickly responded that her son, Louis, is the main reason behind her decision.

"I wanted to make something my son could watch and enjoy," Bullock explained. While the actress also revealed that her 5-year-old adopted child has no idea about the level of her fame and fortune, the "Minions" star said that she'd be happy just to see the reaction of the boy. She shared, "Even though he doesn't know what I do or that it's me, I can sit in the movie theatre and watch him."

Bullock then went on to say, "Nothing makes me happier than hearing that boy laugh. There's physical humor and animation in the movie, so hopefully he'll do that."

The actress shared that she already began introducing her world to Louis but the child seems unfazed by her stories. She said, via BBC News, "I've started telling him that I go and make stories, but he doesn't quite care what that's about - nor do I want him to."

"Minions" is a spinoff film from "Despicable Me" and "Despicable Me 2." Although this is the second time Bullock took part in an animated film - the first was in "The Prince of Egypt" where she voiced Moses' sister, Miriam, this is her debut as a villain. The actress described the experience as a refreshing take on her craft and a good way to release the stress brought about by shooting the film.

She said, "As an actor, being a villain is a great thing. Everyone wants to be able to do that. And we're human beings - we're crabby - so to be able to be mean the entire time you're working? It's a great release."

Bullock also shared some of her difficulties in making the film. Citing her past experiences as her measure that she finally nailed a scene, the actress admitted that such was not the case for "Minions." She revealed, "It was one of the harder things I've done. Every day was different and every day was a struggle," referring to the "actualization" of Scarlett Overkill, according to Herald Scotland.

She added, "Just when I thought I did something well, I would hear, 'we need you to do it again, we didn't get it' - and I'm like, 'how could you not have gotten it?!'" Bullock continued to say, "Then I realized, they're in the other room with their heads hanging low, not even looking at my body - they are just listening, Listening for the sound."

All things considered, however, Bullock said that while "it was not an easy road to get there," she was "so glad" she went through with the project.
