Digital Spy caught up with series star Wyle to find out where the story goes next, how Falling Skies has evolved this year and what role former Lost actor Terry O'Quinn will be playing in the new episodes...
Where does season two of Falling Skies pick up?
"We pick up where we left off in season one, almost to the frame. It picks up with me walking into the ship, then there's a bit of a passage of time, where I'm ultimately released and we don't know what quite happened onboard. But then we start flashing back and filling in the blanks as the episode progresses."
Ben (Connor Jessup) and other characters have been changed by the aliens - will Tom be affected in a similar way?
"The short answer is yes. The longer answer is yes, but we don't know quite how. He comes back to the group and obviously he could be some sort of security risk - he could be an alien plant - and that's certainly cause for concern among the other members of the group. And Tom has misgivings about being a security risk himself."
Are we going to learn more about the aliens and their background in season two?
"Yeah, a lot more. We delve a lot more into the mythology of the whole thing - where they come from, what they want, why they're here. And the interaction that Tom has in the first episode with the Overlord creatures that we introduced at the end of season one really informs him in the second season - there's no more illusions that there's any negotiations to be had. This is going to be a fight to the finish."
What did you make of the reaction to Falling Skies? There were rumours of a second season before the first had even aired...
"There's always rumours, but I think ultimately - given the level of investment that TNT put into the show - they were reticent to pull the trigger on season two until they saw how it was going to perform, at least through the initial few episodes. But everybody was incredibly, pleasantly surprised at how well it was received."
You mentioned at the time that you took on this role for your son - did he enjoy the finished product?
"Yeah, I still blame him for this! He enjoys it very much, he watched the [second] season premiere the other night and he was pretty happy."
Tom and Anne (Moon Bloodgood) shared a kiss in the season one finale - will we see that romance blossom in season two?
"Yeah. It's a tough thing to write inter-personal relationships in a science fiction series where you're always trying to have a constant level of threat. As soon as you write these scenes where two characters take time out of their busy lives to talk sweet nothings to each other, it tends to dissipate that tension! So we had a little bit of trouble on how to execute it.
"We were left with two choices - one was that it was a relationship that played itself out across crowded rooms, with two people wishing that circumstances were different, or he could drag her into the supply closet and consummate the relationship very quickly. First season - we opted for the former, second season - we opted for the latter."
Tom and Weaver (Will Patton) have always had a difficult relationship - how will that develop in season two?
"Well, towards the end of the first season, they seemed to find some kind of simpatico with each other. They seemed to mutually acknowledge the need for the other's philosophy, even if it wasn't their own.
"That momentum carries into season two, where you see them much more on the same page, philosophically. The conflict really comes from other characters."
Terry O'Quinn also appears in season two - what can you tell us about his character?
"Terry comes in [to the show] towards the end of the season. We find out early on in the second season that there's a pocket of survivors existing in Charleston, South Carolina, where they're rebuilding society in some fashion.
"That becomes a bit of a Mecca destination for us, to try to get to Charleston. Everybody entertains different fantasies about what that civilisation's going to look like and what creature comforts may be waiting for them, and what promises of hope and survival could be there...
"And then we get there - not to give anything away, but it's not quite what we imagined. Terry's there and he's taken on a leadership role with those survivors. It comes to pass that he and Tom have quite a significant backstory together, so it's a meeting up of two old friends."
Falling Skies has a great ensemble cast - will we see Tom interacting more with characters like Pope (Colin Cunningham) and Dai (Peter Shinkoda)?
"Yeah. In fact, a lot of the characters that only had peripheral roles in the first season really get promoted to a place of importance in the second season. Pope to a lesser extent, although he's a very significant character - when you plug him in, he's very effective.
"But [as for] characters like Dai, Karen (Jessy Schram)... Ben certainly has a great second season. We took a very bookish, shy academic teenager and turned him a very effective alien hunter. As he goes through this physical metamorphosis, as a result of being harnessed, he becomes... kind of a killer!"
A lot of people will still recognise you as Carter from ER...
"Carter was an interesting character, because he constantly redefined himself as that series progressed. I started in the pilot being comic relief and the young kid in the ensemble. Then eventually I kind of inherited that show and that character went through all sorts of different trials and tribulations - drug addictions, bad relationships...
"So I never felt that that was a pigeon-holing character - it was just a guy that I matured and grew up alongside of. Tom Mason is a moral character and a decent person, and there are a lot of similarities to be drawn between them, but where he starts off and the things that he's called on to do are radically different from anything that Carter did.
"Just from the nature of it being a completely different genre of show, I haven't encountered too much resistance to embracing me in a different part."
Do people approach you now specifically about Falling Skies?
"Yeah, they do. It obviously used to be heavily about ER and then you get a little Donnie Darko and you get a little of these Librarian movies. Now Falling Skies seems to be in the mix."
Falling Skies' second season begins on Tuesday, July 3 at 9pm on FX.
