What was it like making this sequel so soon after the first film?
Alexa: It was really exciting. We filmed in Austin, Texas, first and then we went to Costa Rica, which was so beautiful - monkeys everywhere! It was like a filming vacation, just a big family reunion.
How physically demanding is the film?
Daryl: Well, for "Spy Kids 2", I trained in Junior Lifeguards and did gymnastics. But I have been doing ballet for a long time and tae kwon do, and all of that helps a lot.
Did director Robert Rodriguez ever ask you to do something that was too hard?
Daryl: No. It's just so much fun doing these stunts and all that stuff. And my ballet and tae kwon do really help.
What's your favourite gadget this time around?
Alexa: The spider climbers and Gerti Giggles' hair - I love the flying helicopter on her hair!
Daryl: My favorite gadget was R.A.L.P.H. (Robotic Arachnid Lithium Photo Helper). I love him because he's so tiny - he can do everything from tying a bow tie to using his hi-definition camera to spy for you.
