Joseph Gordon-Levitt is solidifying his reputation as Hollywood's Renaissance man du jour: The 50/50 actor has announced his feature directorial debut, which he wrote and will star in alongside Scarlett Johansson.

Deadline.com first reported the movie news, adding that Gordon-Levitt was tight-lipped on the details. He told the site the movie was a 'sexy comedy' about a 'modern day Don Juan' who works to improve himself (presumably with the help of his leading lady).

Gordon-Levitt got his start on the sitcom Third Rock From the Sun and recently catapulted to A-list stardom via roles in Inception and 500 Days of Summer.

Gordon-Levitt told Deadline.com that directing has long been the goal.

I was a child actor for years and quit at 19, went to school a while, and a big part of why I came back was that I ultimately wanted to make movies, Gordon-Levitt said. I spent a year working with Chris Nolan, Rian Johnson, Steven Spielberg, and I did my best to pay attention. I've also been making short films for a long time now, I've directed a ton of them, and that is a huge part of why I feel comfortable and confident in this.

Gordon-Levitt tweeted the news himself via @hitRECordJoe:

May I humbly present to you the biggest news of my life so far... I'm gonna direct a movie! Wrote it too. And Scarlett's in it with me.

The film, which begins filming on April 16, is produced by Ram Bergman Productions in association with Gordon-Levitt's hitRecord Films.

We will be following the story closely for more details...Can't wait to see it!
