Gillian Anderson: Kate McKinnon as Dana Scully photo tweeted

Gillian Anderson and Kate McKinnon are one step closer to a supernatural buddy comedy.

McKinnon’s scene-stealing Ghostbusters character seems set to inspire a generation of Halloween costumes, but for a young McKinnon, inspiration came in the form of The X-Files‘ Dana Scully. As Feig’s reboot stirs up talk about the importance of representation, an image of McKinnon dressed as Anderson’s beloved skeptic, which the SNL star has shared before, is once again making the rounds.

But this time, it reached Scully herself. Anderson tweeted the picture on Monday with a message to McKinnon: “We have something in common & it’s not slimy green things.”

When Anderson found out about the Ghostbusters reboot during a Reddit AMA in October 2014, she met the news with enthusiasm — and a plea to join the cast. “OH MY GOD, I just looked it up online,” Anderson wrote. “Paul Feig, cast me now! Start a Twitter petition! I’m free!!!!! I’m free I’m free and I’m funny, goddamnit!”

At least one Scully made it into the ensemble.
