In an interview with Variety, Neil Druckmannone of the creators of The Last of Us stated that DLC for Annamothers Ellie was planned. However, Naughty Dog never got anything done.
Druckmann claims to have written a short biography dedicated to Anna after the release of The Last of Us. Moreover, what was originally written served as the basis for an animated short film. However, neither Anna nor the effort to create a DLC for her did much good work.
Anna was re-introduced to the Last of Us series in the "most beautiful and poetic" manner, according to Druckmann, because she had given her the role of Ashley Johnson, the original gaming Ellie. The heroine will likely appear on the screen at the end of the first season.
The third episode of HBO's The Last of Us film adaptation, which focuses on Bill, will be released this Sunday. AND Bella Ramsey, who plays Ellie in the series, believes the show may well get a second season.
