EXCLUSIVE– Dennis Quaid and Zac Efron have boarded an untitled Ramin Bahrani pic, which London-based international sales and production outfit Bankside Films is shopping in Cannes.

Pic, which is to lense in summer, tells the story of a farmer whose manic expansion alienates his sons and devoted wife.

Pic, which comes out of Bankside’s development deal with Christine Vachon and Pam Koffler’s Killer Films, is being shopped domestically by CAA.

KillerMoxie’s Brian Young produces along with Kevin Turen and Justin Knappi.

Andrew Levitas co-produces.

Financiers and executive producers attached to the project include Bankside Films’ Phil Hunt; Michael Benaroya and Rose Ganguzza of Benaroya Pictures; Moe Al Turki and Ron Curtis.

Bankside is also shopping Famke Janssen’s directorial debut “Bringing up Bobby,” which screened to a packed crowd Thursday, Michael Winterbottom’s “Trishna,” and “The Door,” helmed by Istvan Szabo.
