Evangeline Lilly revealed that it wasn't until she was filming an 'intense actor scene' for Ant-Man that it dawned on her that she was working with Michael Douglas.
Lilly has teamed up with Douglas for the first time in Ant-Man - where they play father and daughter Hope Van Dyne and Hank Pym - the second of two Marvel films to hit the big screen this year.
And the actress admits that, at first, she didn't really give any thought to the fact that she was working with a big screen legend.
Speaking to Collider, the actress said: "I distinctly remember the day, the scene, I was working when it hit me I was working with Michael Douglas. Up until that point I hadn't given it any thought. I was like, yeah, OK, great cast, looks good, let's do the movie. I started working without really thinking about it.
"Then I had to do a fairly intense actor scene. Superhero movies don't often have a lot of actors' scenes. He had to bring it and I had to bring it, and somewhere in the middle of that scene the penny dropped, and I went, 'Holy fuck, I'm working with Michael Douglas!'
"From the minute he steps on set, he brings an energy into the world that puts you in your place. I don't mean that in a negative way; I mean that in the most incredible way, like you are immediately transported into the world that you're supposed to be performing in instead of this world, because he goes there, and he goes there 100 percent."
Ant-Man is the latest franchise to be launched by Marvel and will see Paul Rudd take on the title role, while Peyton Reed is in the director's chair helming the biggest film of his career to date.
Another impressive cast has been assembled for the film, as Lilly, Douglas, and Rudd are joined by Corey Stoll, Michael Pena, Judy Greer, and Bobby Cannavale. It looks like we may also be getting a little cameo appearance from Hayley Atwell and John Slattery as Peggy Carter and Howard Stark.
This is the first time that we will have seen Lilly on the big screen since the huge success of The Hobbit: The Battle of the Five Armies at the end of 2014. Ant-Man is another huge role and franchise for the actress as her star continues to rise.
Ant-Man is released 17th July.
