Dilly announced her involvement in the upcoming Columbia Pictures film on her official website. The Tony-nominated actress states that she will appear as cookbook editor Judith Jones opposite Streep in the role of Julia Child. In the new film based on the Julie Powell cooking memoir "Julie and Julia: 365 Days, 524 Recipes, 1 Tiny Apartment Kitchen," Adams stars as an unhappy secretary who seeks inspiration in the recipes of culinary icon Julia Child (Streep). Tucci is cast in the role of Paul Cushing Child, husband to the late master cook.

Ephron, the Academy Award-nominated screenwriter of "When Harry Met Sally," and "Sleepless in Seattle," directs her adaptation of "Julie and Julia: 365 Days, 524 Recipes, 1 Tiny Apartment Kitchen," centering on a 30-ish secretary in a dead end job who decides to reclaim her life by cooking each of the 524 recipes in Julia Child's "Mastering the Art of French Cooking" in the span of one year. She chronicles her endeavors through a blog that becomes popular among the culinary crowd. However, Julie soon learns that "simple French cooking" doesn't always translate to "easy French cooking."

"Julie & Julia" is aiming for a 2009 release.

Adams and Streep will also be seen in the screen adaptation of John Patrick Shanley's Tony-winning drama Doubt. "Julie & Julia" also reunites Tucci and Streep, who appeared together in the 2006 film "The Devil Wears Prada."

Dilly was most recently seen on Broadway in her Tony-nominated performance as Truly Scrumptious in Chitty Chitty Bang Bang. Dilly has also been part of the Broadway revivals of The Boys from Syracuse, Into the Woods and Follies.
