Beyond what I've seen in the movie trailers I have absolutely no clue as to what the Ant-Man origin story, or continued Marvel lore entails. It's a given that the rogue protagonist who plays the role of the miniscule hero is gifted his abilities through the scientifically created suit, and helmet that he wears. In a similar way as the Iron-Man saga we are also presented with a hint via the trailers that a certain someone is out to steal the technology, and that they eventually do. Thus creating the series' villain, the 'Yellowjacket'. I imagine all sorts of shenanigans go on as 'Scott Lang (aka, Ant-Man)' changes sizes, and commands armies of ants to defeat his almost equally sized adversary. There will no doubt be a criminal aspect thrown in as well since Scott led a former life of crime before joining forces with 'Hope Van Dyne/Hank Pym' for the good fight.
For those of you looking for that usual Marvel history lesson fret not as I did do some online digging in order to provide at least a few factoids that relate to Ant-Man's source material. Those factoids go as follows ... Like many of Marvel's masterpieces 'Ant-Man' had his humble beginnings as a guest character in a series that was not his own. In September of 1962, in the pages of a comic book known as "Tales to Astonish #35" the original Ant-Man (aka, Hank Pym) made his debut appearance. Unlike the movie protagonist Hank created, and sported the unique size and strength changing apparatus as a scientific way to combat the world's many problems. You could say he was one of Marvel's geniuses in that respect.
Thanks to the initial trio of comic book legends (Stan Lee, Larry Lieber, and Jack Kirby) whom each contributed to the origin story of Ant-Man the pint-sized hero that was Pym was able to pave the way for other characters of interest to sport the same mantle through the years, but to a different affect. Originally Hank Pym was the scientist who crafted, and the Ant-Man suit/helmet combo, but through chance encounters Pym's legacy was passed on. In the Scott Lang continuation Scott effectively steals the suit to save his daughter only to be caught by authorities, and trained later under the tutelage of Hank Pym himself in order to turn his life around for the better. Of course it goes without saying that the epic saga did not end with Hank, or Scott, and has in fact been picked up to this day as an ongoing series in the ever-expanding Marvel multi-verse. In total there are four men (possibly more ...) who have each donned the Ant-Man guise according to their own unique situations. This includes Hank Pym, Scott Lang, Eric O'Grady, and Chris McCarthy. While the story is a continuation of sorts that has been built upon through the years other famed Marvel artists including 'Robert Kirkman' and 'Phil Hester' have also contributed their visual, and novel interpretation of the characters/situations at hand. With the success of the Ant-Man film, and the revival of the super-hero we may yet see more in the way of comic book spin-offs, merchandise, video games, and films. Let us hope so!
