Sony Pictures has signed on David Koepp to work on two projects in the studio – Billionaire’s Vinegar and Shelley’s Heart.

The first movie is loosely based on the Benjamin Walace book about a scandal that erupted when an auctioned cache of wine purported to have been culled from the stocks of Thomas Jefferson were deemed fake by some.

The latter follows two friends who become bitter rivals for the presidential election, which is won by computer fraud. It is being adapted from Charles McCarry’s novel into a political drama.

Koepp is adapting both films and will direct.
