What is that film about?

Is she aware of this movie?

DIPPOLD:  Yeah.

This is Goldie Hawn’s first feature in like 14 years.

DIPPOLD:  Thank god, it’s Goldie Hawn, so my mom can be excited.

How did it feel to get her back in a movie?

DIPPOLD:  Oh, man, I was the biggest Goldie Hawn fan, my entire life. It’s really, really exciting. And seeing her back in action again, she’s so amazing and so funny. I’m really excited for people to see this.

When you write something for Amy Schumer, do you also write it with Amy Schumer? How much does she contribute to the writing and development, being a writer herself?

DIPPOLD:  Amy is a really, really hilarious writer and did passes on the script. She’s super funny, and I feel like the core of our senses of humor is really similar. It’s actually been really fun. She’s hilarious, and also a great actor. There are moments in the movie where I’m like, “Oh, damn, look at you!” She’s really great. And seeing them together, they’re really awesome together. From the beginning, Amy always pushed for going after Goldie to play the mom ‘cause she was a big fan. So, them together is really special.
