Jesse Eisenberg shot into our lives as Mark Zuckerberg in David Fincher's truly riveting The Social Network, which detailed the genus of Facebook.

Since then, he's done the so-so blockbuster Now You See Me with Woody Harrelson and Mark Ruffalo, the under-seen indie thriller The Double.

He's also signed on to play a character called Lex Luthor in this little film called Batman V Superman: Dawn of Justice. You might have heard of it.

In any case, he's obviously squeezing in smaller budget films between these and American Ultra is one such project.

We can pretty much imagine what the pitch meeting for this was like.

"It's Pineapple Express and Cheech & Chong meets The Bourne Identity and Universal Soldier."

And then a pile of money was put in front of the director. End scene.

So, initial thoughts? Eisenberg could be convincing as a amnesiac-type hitman for the US government, but Kristen Stewart as a slacker girl? GET OUT OF TOWN.
