Last night, actressCarla Guginolive-tweeted during the HBO premiere of last summer’sSan Andreas, where she teased that she has a secret voice role in the movie.

“You might hear me in it if you listen carefully.”

While she wouldn’t reveal what role she has inBatman v Superman: Dawn of Justice, this will be the third time she has worked with directorZack Snyder. She previously starred as Silk Spectre in the filmmaker’s 2009superheroadaptationWatchmenand in his 2011 follow-upSucker Punch. The actress isn’t listed onBatman v Superman: Dawn of Justice’s IMDB page, but a new report claims to know who the actress is playing.

ComicBook.comis reporting thatCarla Guginowill most likely voice the Fortress of Solitude computer inBatman v Superman: Dawn of Justice, reprising that same role from 2013’sMan of Steel.

Following his titanic struggle againstGeneral Zod, Metropolis has been razed to the ground andSupermanis the most controversial figure in the world. While for many he is still an emblem of hope, a growing number of people consider him a threat to humanity, seeking justice for the chaos he has brought to Earth. As far as Bruce Wayne is concerned,Supermanis clearly a danger to society. He fears for the future of the world with such a reckless power left ungoverned, and so he dons his mask and cape to rightSuperman’s wrongs. The rivalry between them is furious, fueled by bitterness and vengeance, and nothing can dissuade them from waging this war. However, a dark new threat arises in the form of a third man: one who has a power greater than either of them to endanger the world and cause total destruction.
