'Indiana Jones was the thing,' says actor.

Even with his coveted role in J.J. Abram’s highly-anticipated “Star Wars: The Force Awakens,” Domhnall Gleeson didn’t know about the annual “Star Wars” Day celebration known as “May The Fourth Be With You.”

That is, he didn't until he received an early Monday text message with the pun that comes from the movie’s iconic catchphrase “May the Force be with you.”

“I didn’t know that was a thing,” Glesson told MTV News’ Josh Horrowitz, before explaining it to his “Ex Machina” co-star Alicia Vikander. “Did you know that? It’s the fourth of May, so they say ‘May The Fourth Be With You.’ Very clever.”

The “Harry Potter” star revealed that, unlike everyone else, he didn’t cry during the “Star Wars” sequel’s second trailer.

“I found it more joyous than that,” he said. “I thought it was really great. It did kind of get the heart pumping and… nostalgia and all the rest of it.”

Gleeson may not have shed any tears when he saw Han Solo in the new teaser, but he almost lost his “you know what” when he met the man who plays him in real life.

“It sounds silly, but Indiana Jones, when I was a kid, more than Star Wars, even, Indiana Jones was the thing,” Glesson said when asked who he was most nervous to meet during the movie's table read. “So yes, meeting Harrison Ford was… everyone was just really nice, but that was one of those things where you make sure your voice doesn’t go high when you say 'hello.'”

In his deepest voice, Gleeson recreated his encounter with the legendary actor, “Hello, I’m also a man.”

“Ex Machina” in is theaters now.
