What were you up to in second grade?

Soon, Racer started drawing out his ideas for the characters that would become the basis for the movie.

How about you be the shark and I be shark boy?"

I just finished the last of theSpy Kids,Spy Kids 3.

There was Disneyland on that planet.

All the greatest things kids want.

So Racer said it’s called Planet Drool because it’s a place that makes you drool.

Racer started drawing his characters for fun.

I had to wear a green screen shirt that was three sizes too small, too.

The final version of Mr. Electric.Everett Collection

We filmed two whole weeks of me with brown hair and he came in and wanted to change it.

I just did a quick Photoshop.

I painted her hair purple.

And then I painted it pink.

And I said, “Oh my God, that’s it.”

You know, like getting into trouble here and there.

Dooley:Taylor [Lautner] and I’s family became really close.

We lived right down the street from each other and had no clue.

Then we went to go filmSharkboy.We used to play “shark in the dark.”

I think Taylor invented this game.

We would turn off all the lights and he would mostly always be the shark.

It’s basically tag in the dark.

Rodriguez:Our studios are called Troublemakers studios, but around that time, we called it Babymaker Studios.

They all had children and little babies.

We had play areas and it was just super fun.

A fan video online of the sequence has12 million views.

I came up with a Danny Elfman-bang out song fromSpy Kids.I played it for Racer recently.

It feels like it’s fromNightmare Before Christmas, you know, it’s very much in that mold.

Just how iconic that was for them.

It’s pretty funny.

Robert was probably like “keep your eyes closed.”

I was probably peeking because that was a fun day on set.

Rodriguez:I do remember Taylor being nervous for her first kiss.

So we said “Okay, here’s a green pole.

But that wasn’t the only prank on set.

Boyd:I remember hearing about [the pole prank].

I remember the grips and the whole catering crew having a prank battle themselves.

Rodriguez:We were shooting this at the same time asSin City.I was making two movies at once.

The kids would come in the day, and then the older actors would come in later.

It was one that’s very dark and then very light.

You need that balance.

It’s like a family movie for families at all.

Rodriguez:[Dooley] looks incredible like she stepped into her own sequel as Lavagirl.

It’s a big movie.

It’s a big cast.

And it’s gonna be it’s super fun.
