Mark Hamill was 25 when "Star Wars" was released in May 1977. New franchise star John Boyega just turned 25 on March 17, 2017. Hamill's Twitter is a gift that keeps on giving, and this week he posted 1) possibly the first-ever photo of Luke on the set of "Star Wars," and 2) an adorable birthday shout-out to his "son," Boyega.


Hamill also got candid when a fan asked, "At that very moment, were you thinking 'This is gonna be my big break' or 'Crap, it's early, dusty and way too bright'?"


Boyega's Finn had his own big start in the "Star Wars" galaxy in "The Force Awakens," and he'll join Hamill's Luke, Daisy Ridley's Rey, and the extended fam in "The Last Jedi."

Hamill and Boyega shared a very father/son exchange to celebrate the young star's 25th b-day:


Boyega was actually on the set of "Pacific Rim 2" for the milestone:


"Star Wars: The Last Jedi" opens December 15th, 2017. "Pacific Rim: Uprising" is scheduled for release February 23rd, 2018.
