Tom Vaughan (What Happens in Vegas) is to direct GreeneStreet Films and Das Films’ Boomsday, adapted from the Christopher Buckley comic novel.

Ron Bass (Rain Man) and Jen Smolka wrote the script. GreeneStreet will finance and produce with Sriram Das of Das Films, with production set to begin in the second quarter of 2011.

Boomsday revolves around a Washington DC publicist and blogger who attracts the attention of a handsome politician and finds herself romantically and politically in over her head.

“I very much look forward to working with Das Films and GreeneStreet in bringing this hugely entertaining comedy to the screen,” said Vaughan in a statement. “Ron Bass and Jen Smolka have written a wonderful screenplay (based on the book by Christopher Buckley) laced with compelling drama, bitter sweet romantic comedy, acerbic wit and razor sharp satire.”

Glen Basner’s FilmNation is selling international rights to the film through its partnership with GreeneStreet.

Vaughan, who previously made Starter for Ten and Extraordinary Measures, is represented by CAA. Buckley and Bass are both represented by ICM.
