The Golden Globes is changing or clarifying some of its rules — with one that may as be called "The 'Big Little Lies' Rule.'

The Hollywood Foreign Press Association updated rules and regulations on its website that will impact this year's Golden Globes race. One change affects limited series like "Big Little Lies," which swept its category in January, winning Best Miniseries or Television Film and Best Actress (Nicole Kidman), Supporting Actress (Laura Dern), and Supporting Actor (Alexander Skarsgard).

When HBO submitted the show for consideration, it was technically a one-off limited series. But then, the network renewed it for a second season just after nominations were announced. So, the HFPA's new rule clarifies how a show like "Big Little Lies," originally created as a limited series but extended as an ongoing one, will be handled:

A television limited series that is later renewed for an additional season shall be classified as a series or again as a limited series in that later season depending on the degree of continuity in theme, storyline, main characters and production supervision from the original limited series to the later year of the series.

The other notable changes involve the classification of supporting actors in films and television programs. For instance, one rule now reads: "Actors in ensemble casts in television programs with comparable roles should be classified as all lead or all supporting actors."

That could affect nominations for shows like "Game of Thrones," where cast members like Kit Harington, Emilia Clarke, Peter Dinklage, and Lena Headey have comparable screen time. This means they would all need to be submitted as leads or as supporting actors.

Meanwhile, another rule states: "Supporting cast members in a motion picture must appear in a minimum of 5% of the motion picture's total program time." So, no flashy cameos stealing the show and Golden Globe.
