Columbia Pictures has signed the writing team of Tim and Tom Mullen to adapt Antony Moore's comedy novel The Swap.

The story centres on an out-of-shape comic book dealer who loses a priceless part of his collection and follows that up by getting involved in romance and murder at his high school reunion.

Columbia vice president Rachel O'Connor will oversee for the studio and John Calley Productions' Calley, Diana Napper and Lisa Medwid will produce.

The Mullen Brothers are represented by Ava Jamshidi at ICM, as well as Kersey Management and Adam Kaller at Hansen, Jacobson, Teller & Hoberman.
