Mumolo tells WENN the project has "a different tone from Bridesmaids", and she and Wiig will portray the women.

"We're writing it for the two of us to be in," she tells WENN.

Mumolo also confirms she is co-writing "a modern day adaptation of Auntie Mame" for Tilda Swinton with Moneyball screenwriter Stan Chervin, adding, "It's taken from the book, so it's a very different tone of other movie versions that were made."
