“It was thrilling to have him around, especially on camera,” Steenburgen says of Feig.

I ruined quite a few takes from laughing because of him.

We had the best time together.”

Steenburgen says with a laugh.

“I’ve done it maybe 20 times too.

Peter is just one of my dear friends, I love him so much.

The idea of him not being there, nobody had to work at any tears.

Honestly, we had to work atstoppingthe tears.

And that’s the truth.

I still don’t even accept it.

No, you have to figure out a way for Peter to be there somehow.

He’s just such a part of all of this and a part of all of our hearts.

He’s so special.”

I think people will connect in a very deep way because of this.”

Zoey’s Extraordinary Playlistairs Sundays at 9 p.m. on NBC.
