We told you about this top secret movie movie project titled, Transcendence earlier this month when Rebecca Hall (Iron Man 3) joined Johnny Depp and Paul Bettany (The Tourist), and the smallest plot we still have to go on is that Johnny Depp is playing some sort of scientist who uploads his mind to a computer.

Well the mystery may continue but the casting goes on with American Horror Story’s deliciously neurotic Hayden played by Kate Mara (who has also most recently been in Netflix’s House of Cards) coming into the Transcendence circle of trust. This latest casting and news of a “big budget” is according to Vulture.

We will keep you posted on Transcendence starring Johnny Depp, Paul Bettany, Rebecca Hall and Kate Mara which is slated to hit theaters April 25, 2014.
