From art-museum outings with 6-year-old daughter Suri to a guest appearance on Project Runway â€" and a little ice cream in between â€" Katie Holmes has maintained a busy schedule since filing for divorce from Tom Cruise last week.

And she's not slowing down as she shifts her career into a higher gear.

Next week, Holmes, 33, is due to begin production on a new film, Molly, which she co-wrote and is co-producing. In a case of life imitating art, the plot follows the life of a single mother and her daughter, according to a source. (Holmes is seeking sole legal custody of Suri.)

Filming is scheduled to last until about August in New York City, where Holmes recently moved into a new three-bedroom apartment with Suri.

The actress, who wrapped a modern film retelling of Anton Chekhov's The Seagull in May, is then due on set in the fall to shoot Responsible Adults, a romantic comedy about a guy (Chace Crawford) who discovers that his crush was his babysitter 15 years earlier.

She's also planning her first-ever show at New York's Fashion Week in the fall for her clothing line, Holmes & Yang.

Amid her jam-packed schedule, Holmes and Cruise's lawyers are currently working on a divorce settlement between the two stars.

"Neither of them wants this to be hashed out in public," a source told PEOPLE.
