We Came from Outer Space

The aliens have arrived, and they’re ready to party. Join us Halloween night for a creep-tacular celebration of the golden age of alien invasion.  

Journey through the cosmos, where flying saucers fill the skies and the line between earthling and extraterrestrial gets delightfully blurry. Inspired by the atomic-age thrills and retro-futurist style of 1950s and ’60s sci-fi, Fashionably Undead: MOPOP’s Halloween Bash invites you to an intergalactic encounter unlike any other.

Prepare for an evening of dancing, out-of-this-world activations, and lurking around the museum after dark. Earthlings, aliens, and everything in between are welcome.
