English actress Emilia Clarke is no stranger to keeping project details a secret to the public ever since she has starred in HBO's hit series "Game of Thrones," which values secrecy quite strictly that even the cast have not been told anything about what goes down in the final season. However, she is apparently even more overwhelmed by how little she can say about a new project she is working on, which is Disney's untitled "Han Solo" movie.

In an interview with Los Angeles Daily News, the 30-year-old actress revealed that keeping "Star Wars" secrets is "even scarier" than spilling details about "Game of Thrones." In fact, she is not allowed to say anything about the project at all, not even her character name.

When the publication tried to get her to say something about the upcoming "Star Wars" anthology film, she said, "I genuinely can't tell you anything other than Alden [the actor who plays Han Solo] is magnificent, and it's a delight to do something on that level with really cool actors and nice people." Then, she added, "But it's even scarier talking about that than Game of Thrones."

Apparently, Disney is even stricter than HBO when it comes to keeping its actors tight-lipped.

As of now, the only few things the public knows about the upcoming "Han Solo" film are the actors and their characters, except for some, including Clarke's, and that it will cover six years of young Han Solo's life, from age 18 to 24. According to Screen Rant, the movie is most probably going to show how the young smuggler met Chewbacca and how he got the Millennium Falcon from young Lando Calrissian, to be played by Donald Glover.

The untitled "Han Solo" film is scheduled to hit theaters on May 25, 2018.

Clarke's credits include "Me Before You," "Terminator Genisys," "Dom Hemingway," and "Spike Island." She also stars in the film "Voice from the Stone," which has recently premiered in the United States.
