Is the 39 clues series going to be a movie?

The film was originally in development at DreamWorks in 2008, with Shawn Levy attached to direct and produce. In late 2010, Dreamworks had put 39 Clues into turnaround. Nickelodeon Movies later acquired the rights in 2014, with Michael De Luca attached to direct and Dan McDermott to produce.

The film adaptation went through several delays and changes in production, and there have been no recent updates about its status.
