The 45-year-old actor has praised his 'Jason Bourne' co-star for her versatility and ability when it comes to her acting.

He said: "I just think of these once-in-a-generation actresses who kind of explode onto the scene and what strikes me about her is I can't see where her limits are. There's been six or seven recent performances and they're all really different and they're all going in different places and I don't see the boundaries yet. I'm really excited to see what she does next.

"She's going to keep working with great people because great people all want to work with her. In my experience, I knew a lot when I was 27, but the next 18 years were, it was nothing but fun because I was doing what I loved to do and kind of by osmosis, you get better at it because of the people you're around and working with. I don't know where she's going to go but I'm excited to see it."

And Matt is so glad the movie's director Paul Greengrass was able to sign up Alicia, 27, for a role in the film.

He added to PEOPLE magazine: "We were lucky to get her. Everyone in Hollywood is trying to get Alicia in their movie right now."

Meanwhile, Alicia previously admitted she feels "scared" her career dreams are coming true.

She said: "To be quite honest, it's nerve-racking, the way these films sort of piled up. It's a mixed feeling when everything you've ever wanted in making films is coming true, and yet you feel scared because it's happening all at once.

"Suddenly you're in rooms with people you've looked up to for years, the Judi Denches. You wonder if you're good, if you have what it takes. You carry an anxiety around with you - I've met many actors now who will say this - and the lonely feeling that this could be your one chance."
