Yes, there is a Spy Kids 4 in the works. Robert Rodriguez is planning to re-boot the series, since he is the one that directed the first three. Jessica Alba will play a retired spy who is a mother of a baby and two preteen step children.
The Spy Kids two leading stars, Daryl Sabara and Alexa Vega aren’t kids anymore. That’s the reason they had no choice but to re-boot the franchise but Daryl, Alexa, and Antonio Banderas are expected to return for smaller roles.
Don’t be surprised that they could get Justin Bieber to star as one of the new Spy Kids.
