— -- It's been almost a year since the "Star Wars" community lost Carrie Fisher at 60 years old.

But with Fisher reprising her role as Leia one last time in the upcoming "The Last Jedi," cast, crew and fans will get a final chance to enjoy Fisher's legendary portrayal of the no nonsense, kick butt princess turned general.

No one is more excited to see Fisher back on screen than her "space twin," Mark Hamill, who once again plays Leia's brother and Jedi master Luke Skywalker in the highly-anticipated blockbuster.

Hamill, 66, spoke about his fond memories of his dear friend on a recent visit to the set of "Popcorn With Peter Travers." He also recalled the last prank she pulled on him before she died on Dec. 27, 2016.

"We were sort of in an unofficial contest to get to 1 million Twitter followers first," he explained of their competition from summer 2016. "She was 63,000 ahead of me ... I said, 'Game on girl!'"

As of now, Hamill has more than 2 million followers and Fisher posthumously has 1.19 million. Hamill, who was trailing in the beginning, said he started pulling these ridiculous stunts like offering up exclusive "Star Wars" clips to gain followers and catch up to Fisher.

"I felt bad, I was really gaining," he said, so he also came up with a plan where the two could cross the milestone together, as on-screen brother and sister. "I sent her an email and I said, 'Hey Carrie want to explode the internet?' ... We had never seen our wax figures at Madame Tussauds."

The plan was to go, take pictures with the wax Luke and Leia figurines, then post on the internet to fans' delights. But Fisher never emailed him back.

"Three of four days later, there she is at Madame Tussauds posing with my figure, posing with her figure, I went, 'What!?' I was livid," he said. "I went to the studio the next day [and went right to her trailer]. I said, 'Carrie, what did you do!? It was like ... you threw the party and you didn't invite me!'"

According to Hamill, she just looked up at him and said, "Should have I not done that?"

Hamill couldn't stay mad at her.

"I loved her so much," he said. "She made everything fun."

In addition to that story, Hamill spoke about the brother and sister like relationship the two had in real life.

"We had a really mercurial relationship ... she could make you feel like the most important person in the world," he said. "Then the pendulum would swing, it was like a real sister."
