Jessica Alba's Baby (And It Is Overflowing Diaper) Inspired 'Spy Kids: Constantly within the World' (VIDEO)

Who understood that Robert Rodriguez's bloodstream-drenched knife-fest 'Machete' will be the inspiration for that 4th 'Spy Kids' movie? The director told Moviefone that seeing Jessica Alba's attempts at handling her baby's "overflowing diaper" while filming the cult hit sparked the concept for any spy mother by having an infant with you. Alba herself, who had her second baby days following this interview, agreed it's difficult juggling movies and mommyhood simultaneously. We also sitting lower with 'Spy Kids 4' stars Jeremy Piven, who were built with a blast playing multiple figures new kids Rowan Blanchard and Mason Prepare and 'Spy Kids' veteran Alexa Vega, who told us coming back towards the franchise was "surreal" which, yes, she still will get acknowledged as Carmen Cortez. Joel McHale also shared an Aroma-Scope (the scratch-and-sniff card being provided throughout all tests) secret around: "My character has the aroma of lavender." Okay, that isn't among the smells on the Aroma-Scope card, but nice try, funny guy.
