If Luke Hemsworth could turn back time, he'd turn it back to the '80s.
So, to celebrate his 36th birthday over the weekend, the Westworld star decided to throw an '80s-themed birthday party. Guests including Laural Barrett, Mark Furze, Miley Cyrus, Eric Haskell, Jaime Haskell, Katie Jensen, Lisa Oberwager, Jen Rossi and Courtney Tyler Seashols—plus brother Liam Hemsworth and wife Samantha Hemsworth—got into the spirit, wearing colorful costumes inspired by Luke's decade of birth. The actor even dressed up as comic book and cartoon character He-Man. As he joked on Instagram, "Fabulous secret powers were revealed to me the day I held aloft my magic sword and said 'by the power of greyskull!'"
Luke took the '80s theme very seriously. His birthday cake was modeled after Pac-Man and Rubik's Cube, and his wife shared a number of Polaroid pictures with her Instagram followers.
