Anna Heinrich grills the Rough Night cast on their Aussie accents and hen's night tips: Watch!

What do you get when Anna Heinrich joins Scarlett Johansson, Kate McKinnon, Zoe Kravitz, Jillian Bell, and Ilana Glazer in the same room?

Magic.

TheFIX sent The BachelorThe Bachelor to New York to interview the Rough Night cast about the film, which sees five friends band together as a wild bachelorette night goes seriously wrong.

In the comedy (in Australian cinemas now), Ghostbusters star Kate puts on an Australian accent to play her character, Pippa. So naturally, Anna asked all the ladies to show us their best Down Under accents during our exclusive interview.

The results were…downright hilarious.

While Zoe nailed "throw another shrimp on the barbie", Scarlett struggled with a basic "How you goin', mate?" And Jillian's "She's a bloody good sheila" is PRICELESS.

The cast even had some hilarious advice for 30-year-old Anna's hens night ahead of her wedding to fiancé Tim Robards.

"I've probably been planning my hens party since before I even met my fiancé," Anna admitted, before seeking their tips.

"Well, you should have sex with another man," Jillian deadpanned. "Or a woman."

"Maybe one of each!" chimed in Ilana.

Scarlett, meanwhile, encouraged her to do "a mountain of cocaine" and go on a "three-day drug binge".

When Anna jokingly asked the girls if that's what they did to prepare for the film, Kate gave the best answer of all time.

"There was actually supposed to be a sixth character, and she died [while prepping]," Kate joked. "The actress did pass, so it was just the five of us."
