Wilson, 35, said she agreed with Mann when it comes to awards season.
She said: "I find it interesting when I'm watching the Globes and there's a comedy category. I think not all films nominated fit into that category. But I love working in comedy, I have so much fun working in it.
"I particularly love that I'm being chosen to star in strong, female ensemble movies. First I did Bridesmaids and then the Pitch Perfect franchise and now this.
"I love the girl power," she added.
Fifty Shades Of Grey star Dakota Johnson, 26, said the fun never stopped when she was working with Wilson.
"Rebel was amazing to work with, she's smart and funny and her brain never stops working," she said.
"It's not easy being funny, it's something people have in their bones it can't be taught."
Also starring in the movie is new-comer Alison Brie, 33, who spoke about the shift in society and what is expected of women.
Brie said: "We're shedding the stigma that we need men for power and money and the idea that we were only meant to be a wife.
"It's very old-fashioned thinking, but now that women can have children later and women are focusing on their careers longer, you can really be single and it isn't a negative thing."
How To Be Single is released in New Zealand cinemas on February 18.
