According to Arnett, Slade will play an integral part in their quest for big-screen stardom.

I know this movie is about the Teen Titans trying to get their own movie.

Deathstroke has been played by many people.

This Slade is much more childish.

He kind of lowers himself to their level with regards to being a nemesis.

Hes not as potentially scary as hes been in the past.

Youve also voiced Batman in theLEGOmovies.

Which one did you have more fun doing?You cant pick your favorite kids.

Ive had a lot of fun playing and continuing to play Batman as we move forward in theLEGOuniverse.

[This was] fun because Batman is not a villain.

Its fun to play the villain.

Theyre very different, Ill say that.

I met the guys over atTeen Titansa couple years ago.

Animation and said Id really like to meet the guys.

What do you think?

Would you come and sort of jump in on the process and help us get this made?

I said, For sure.

Then after that, we werent really sure.

We didnt have a script or anything at that point.

We thought, Well, if I was going to have a voice role, what would it be?

So I said, Yes, Ill do whatever you guys want.

I think the idea that Oh my gosh, another superhero movie where would that fit in?

just really made them laugh.

In a lot of ways, its really a comedy show wrapped up in a superhero veneer.
