It's already been five years since the first episode of "Game of Thrones" aired in 2010, so of course the younger cast, namely the children of the series, are all but grown up at this point, and that includes the young actress who plays fierce Arya Stark - and Maisie Williams' net worth is living proof of this.

While Maisie Williams' ne worth obviously comes mostly from her work in the HBO series based on George R. R. Martin's books, in fact the young actress has been involved in a series of projects throughout her short career.

Besides her role as one of the audience's favorite members of the Stark family, Maisie Williams' net worth also stems from her voice work in the cult Adult Swim show "Robot Chicken," besides appearing in a few different side projects such as a television film called "Cyberbully," besides an upcoming project with Justin Timberlake's wife Jessica Biel called "The Devil and the Deep Blue Sea."

One piece of casting rumors could prove to be very interesting for Maisie Williams' net worth in the near future, as she's rumored to be in talks to star in the cinematic version of the game "The Last of Us," taking the role of Ellie in the project.

These days, while the big paycheck continues to rise Maisie Williams' net worth as she films the sixth season of the HBO series, fans eagerly await her appearance in another pop culture phenomenon, as the British star is set to make an appearance in the long-running BBC science fiction series "Doctor Who," these days starring Scottish actor Peter Capaldi as the Time Lord.

According to Variety, Williams' character in "Doctor Who" is going to be "surprising," in the words of showrunner Steven Moffat, and there was even a recent teaser released featuring her.

Currently, Celebrity Net Worth lists Maisie Williams' net worth as $3 million - and she's only 18!
