ET caught up with the 37-year-old actress on the red carpet, where she gushed about making her directorial debut in her new movie, All We Had -- but also admitted that it was tough to both direct and act in the project.

"I had a lot of notes of what I wanted to do, but it's still… it's a big risk," she revealed. "It's a sense of nervousness because any project that you put out, you want people to like it and see it, to experience and connect with it, I suppose, but it's really thrilling.

"I'm so grateful that I got to do it," she shared, adding that she plans to celebrate the film's December premiere with friends in theaters.
