Brie Larson was on "The Tonight Show Starring Jimmy Fallon" on Wednesday ahead of the release of the most anticipated film of the year "Avengers: Endgame," which premieres on April 26.
She couldn't talk about that, though.
The host, instead, turned his line of questioning to the star's monumentally successful "Captain Marvel," which has earned around $1.1 billion globally at the time of writing.
Apparently, Larson got a surprise visit on set from her friend Samuel L. Jackson, whom she directed in her film "Unicorn Store" (which is now on Netflix).
Knowing Larson was a huge "Star Wars" fan, Jackson turned up with a significant prop on a significant date, May 4, the actress told Fallon.
"He walked in and dropped this bag on my lap that was this kind of beautiful silk bag," the actress said.
"I opened it and it was his lightsaber, and I just immediately burst into tears."
May 4 is otherwise known as "Star Wars Day" because of the day's similarity to the franchise's famous phrase: "May the force be with you."
"May the fourth be with you," Fallon explained.
"Big day for 'Star Wars' fans," Larson confirmed.
Jackson played the Jedi Mace Windu in "Star Wars" episodes one and two — a character famed for his unique purple lightsaber.
"I don't think he's supposed to have it," Larson joked. "I'm not even sure if I'm supposed to say that he has it.
"I'm sure someone has emailed him five million times saying, 'Mr Jackson we really need this back.'
"He's got cinematic immunity in a way, though," she added, "he does whatever he wants."
According to Larson, the lightsaber had some weight to it and she said that Jackson got to pick it out himself: "That's one of the perks of being a Jedi."
Most notably of all, though, the actor apparently had the weapon engraved with something so quintessentially Samuel L. Jackson that you couldn't make it up.
"It says: 'Bad Motherf-----,'" Larson said.
