Julia Roberts is to star in her first television series. The actress will appear in a TV adaptation of Maria Semple's novel Today Will Be Different, which was published in September. Semple will write the mini-series herself, while Roberts's own company Red Om Films will produce it. Roberts has previously appeared as a guest star in such TV shows as Friends and Law & Order, but this will be her first lead role in a series. It has not yet been confirmed which network will broadcast the show.
