The 'Ghostbusters' Reboot's Girl Power Is at an All-Time High - See the Pic!

The girl power behind the Ghostbusters reboot goes way deeper than just its leading ladies.

Melissa McCarthy tweeted a group photo of the film's female cast and crew members on Tuesday. In the pic, the dozens of women pose while holding signs bearing their business titles, such as "actor," "cast assistant" and "stunts."

Up front were stars McCarthy, Leslie Jones, Kate McKinnon and Kristen Wiig, holding a banner that read "Girl Power."

"Three cheers to Ellen from all the remarkable women of #Ghostbusters," McCarthy wrote as the caption. "When we stand together we are unstoppable! #GirlPower."

McCarthy seems to be referencing Ellen DeGeneres' new children's clothing line for GapKids, GapKids x ED. The line debuted with an empowering fashion show that featured Kayla Kosmalskin, a 9-year-old model with Down Syndrome, and 13 other "power girls," four of whom have disabilities.

DeGeneres responded to McCarthy's tweet with an appreciative tweet, writing, "This just made my day."

Earlier this month, the new Ghostbusters cast made a surprise visit to a children's hospital. Check out the video below.
