Case in point, Jason Sudeikis yells, as a play on his character, Seeing red!
; Bill Hader cries out, You are getting under my skin!
ENTERTAINMENT WEEKLY: How did Sudeikis bring humor to the film through his sarcastic, hot-blooded character, Red?

That also comes down to the characters; you put Red in situations that audiences should identify with.
REILLY:Red basically says and does the things that we would love to do.
It can be very funny to watch, and we just took that idea and kept running with it.
The first question we asked ourselves was, What makes you angry?
Wed ask each other, What kind of things irritate you?
Do you feel like that perception is changing at all?
Or is anger included in animated movies, but is hard to pull off?
KAYTIS:I think its a result of modern films maturing.
You see films likeInside Outor evenAngry Birdswhere youre exploring, What are real emotions that people have?
and How do you deal with those?
and that was a really fun and challenging part of making this film.
In doing so, and approaching those more difficult subjects, it creates a far more emotionally satisfying movie.
Thats kind of the beauty of attacking subjects like, What makes you angry?
You have that extra material to mine from, and its actually a great comedy challenge.
Our movie operates on the sophistication of any Judd Apatow comedy, or anything like that.
That was the approach and thats Vittis background as well.
He wrote onThe Simpsons,Arrested Development, [The Office], [Saturday Night Live].
Theres fun in it, but the best laughs come when you place them against something.
Thats why comedy is kind of born out of tragedy.
Its the juxtaposition of lots of emotion that makes the laughter work.
What did they bring comedically or emotionally?
KAYTIS:Josh is Chuck in a funny way.
We dont really speed his voice up in the film.
Danny McBride, Maya Rudolph, Bill Hader, theyre all such great improvisers.
REILLY:Every single one of them brings something different.
Maya was hilarious and could push the character in ways that we couldnt even think of.
Every single one of them, even the smaller roles Ike Barinholtz, Hannibal [Buress], Smosh.
We did lots and lots of recording sessions.
I think we probably did 90+ full days with our cast.
It was always great fun.
Were going to try lots of stuff and see what goes and what doesnt.
