What is it with the cast of Mad Men and science fiction? Last year, Jon Hamm starred in the terrific, special Christmas episode of tech-fear anthology show Black Mirror. John Slattery reprised his role as Howard Stark in the recent Marvel movie Ant-Man. And now Christina Hendricks is guest starring on this week’s episode of Dan Harmon and Justin Roiland’s sci-fi sitcom, Rick and Morty.

On the show, which airs at 11:30 p.m. ET on Sunday, the actress plays an old girlfriend of Rick’s who has the ability to create a hive mind and has taken over an entire planet. You can see a clip featuring Roiland’s Rick and Hendricks’ Unity, above.
