Hamill's tweet compiled shots of Star Wars-inspired marchers: one sees a woman raising a sign depicting Carrie Fisher as Princess Leia with the caption "we are the resistance," while another sees a woman donning Leia's classic garb with a sign reading "don't Leia hand on my healthcare."
"A woman's place is in the resistance," reads another sign held by a marcher also representing Leia's iconic A New Hope look.
"Carrie would be SO proud," Hamill wrote in a tweet. "Resist. Register. VOTE!" Hamill signed off with the hashtag, "#ReSIStanceSISters."
Star Wars fans took to Twitter to show off other signs paying homage to a galaxy far, far away, representing with the tagline "The Fempire Strikes Back."
One sign, featuring Fisher's Princess Leia likeness and the American flag, read "Keep calm and Carrie on."
Others still showed their support for the Women's March borrowing a phrase from Rogue One and utilizing Fisher's visage as General Leia Organa in the Star Wars sequel trilogy, while another fan showed off their Leia-themed tattoo.

The marches, launched in support of women's rights and female empowerment, saw countless supporters — both men and women — taking to the streets nationwide over the weekend. The demonstrations marked the anniversary of President Trump's inauguration.
Hamill and Fisher recently co-starred in Star Wars: The Last Jedi, Fisher's last time as Leia. Fisher passed away in December 2016 at the age of 60.
