In "Ender's Game," Earth has been battle-scarred by an alien invasion, and the military has taken to recruiting very young men and women to become the next defenders of our world.
Harrison Ford plays the head of the battle school that trains these future leaders.
"Historically it's been the case that the youngest, fittest, lowest on the social totem pole are the ones that have always been pushed to the front of the battle line, and the character that I play is meant to be both the mentor and manipulator of them," said Ford.
Viola Davis also stars as part of the training team. She's responsible for the psychological well-being of the children who are in the program.
The novel "Ender's Game," was geared toward young adults, but Davis thinks the film can resonate with all ages.
"I always feel like art always imitates life, and I think art at its best finds us at a time when we're able to receive it. I don't know if we would have been ready to receive this in the mid-1980s, but right now after Iraq and Afghanistan and what we know about social media, technology, video games and all of that, I think it's the right time," said Davis.
The best-selling sci-fi novel "Ender's Game" took 28 years to make it to the big screen, but apparently fans thought it was worth the wait. The film took the top spot at the weekend box office, raking in $28 million in its opening weekend.
