It was reported back in May that the alien-invasion drama was close to being picked up for another run.
"Everybody's fingers are crossed that if it gets a good audience, it gets renewed and it'll come back for season two and be really fun," Verheiden confirmed to SFX.
"When you get to the end of the first season you'll see that we've just scratched the surface about what's going on, so there are definitely long-term plans."
Verheiden added that production on the show's first 10-part season had been "the usual headlong rush into chaos".
"At the end of [that chaos] you hope you have a great show, which is true of every show I've worked on," he explained. "What we did have, though, was enough time to do the CGI effects and the various creature effects. Those didn't have to be rushed."
Falling Skies begins tonight at 9pm on FX in the UK. The first season continues on Sundays on TNT in the US.
