What the hell happened to my life, Im not who I thought I would be.

I think those things are something weve all gone through.

Chris Klein:The universal themes of this movie are what make it attractive to everybody.

I think thats pretty unique to our franchise.

What did you initially think when the fourth movie was pitched?

But once I saw what we were doing, I realised that we werent tarnishing anything.

Chris, was there a particular reason you didnt appear in the third film?

CK:No, those kinds of decisions come way above my pay grade.

They decided to makeAmerican Weddinga different way, and Oz and Heathers storyline was kind of played out.

It is what it is, Im just grateful to be invited to this one.

It has similar themes in that every character has a clear, concise arc in this movie.

We all know how sequels work, with movie studios as money factories, trying to make a profit.

In this particular edition, I felt a renewed vigour with the rest of the cast.

Would you guys have done some of the things that Jason Biggs has to do in these movies?

I havent done that in my career.

So Jon and Hayden didnt ask, Biggs asked them.

CK:I dont know if theres courage in showing your penis in a movie.

What I love is within the frame work of the scene, the way that its done.

Thats what makes it funny.

EKT:Its not what it looks like.

The reason thats funny is because Jason means that.

There are a million and a half actors that cannot do that.

Its a giggle but Biggs actually means it.

Those moments throughout the films are the reasons why.

EKT:So many people tell us, we grew up with you guys.

With that, they werent the only person terrified of being 17 years old.

How well do you think it represents youth culture in America today?

The box office around the world is incredible, so I guess it touches on universal themes.

Everyone seems to relate to the awkwardness of being a teenager, or even a 30-year-old.

Did either of you have any input into how your characters would develop?

That was part of their process.

CK:I didnt have any input because their pitch was tremendous.

They said he was a sports broadcaster, in a hip-hop dance competition, and I said awesome!

They said he was still in love we Heather, and I said, yeah, he is.

I give them all the credit in the world.

Eddie Kay Thomas and Chris Klein, thank you very much.
