New Regency is negotiating with Ewan McGregor to topline the Marc Forster-directed drama “Stay.”

McGregor will play a therapist at an Ivy League school who tries to prevent one of his students from committing suicide.

“Stay,” which has “Sixth Sense”-esque supernatural overtones, was scripted by David Benioff, whose epic “Troy” is in production with Wolfgang Petersen directing Brad Pitt and Eric Bana.

The script for “Stay” was the subject of one of the biggest spec auctions in recent memory; New Regency won with a bid of $1.8 million.

David Fincher originally was slated to direct, but Forster (“Monster’s Ball”) came aboard the film in the spring.

Tom Lassally is producing, with Eric Kopeloff and Guymon Casady exec producing. Regency’s Sanford Panitch and Kara Francis are overseeing the production.

McGregor is onscreen in New Regency’s “Down With Love” and next will be seen in “Big Fish” opposite Albert Finney.
