In 2005, Anderson starred in the BBC's 15-episode miniseries Bleak House, based on the novel by Charles Dickens. According to IMDb, she earned nearly $700,000 for her work on the show. In 2006, she co-starred in the movie The Last King of Scotland.

Anderson returned to the small screen to star in Hannibal from 2013 to 2015, and she also starred as Detective Superintendent Stella Gibson in BBC's thriller The Fall for three seasons, between 2013 and 2016. Anderson also filmed two revival seasons of The X-Files, which aired in 2016 and 2018.

As further evidence of her range as an actress, Anderson starred as Blanche in A Streetcar Named Desire at London's Young Vic Theatre in 2014 (via The Guardian).

Anderson also stars as sex therapist Jean Milburn in the popular Netflix series Sex Education, which premiered in 2019 and is slated to return for its third season sometime in 2021. Although her stint on The Crown was only for one season, she's already preparing to play another historical figure. It was recently announced that Anderson has been cast as Eleanor Roosevelt in the upcoming miniseries The First Lady, which will air on Showtime (via Deadline). It's safe to assume she'll bring home a hefty paycheck (and potentially a few more awards) for this series as well.

During her successful and award-winning career, Gillian Anderson has amassed an impressive net worth, which is estimated to be $40 million, according to Celebrity Net Worth. No doubt that will continue to grow.
