Josh Hartnett time-travels with his Slevin director Paul McGuigan

Where has Josh Hartnett been hiding?

Or his movies, anyway — his last major release was 30 DAYS OF NIGHT (though he’s apparently filmed five or six others since then).

Hartnett will reportedly reunite with Paul McGuigan, who directed him in WICKER PARK and the underappreciated hitman movie LUCKY NUMBER SLEVIN.

Their latest project is a contemporary sci-fi thriller called TOMORROW, described as being in the vein of MEMENTO.

The cryptic synopsis: Max Martin is desperate to save his family on the day of their murder but he can’t control the short-term time travel phenomenon he’s trapped in.

The movie is expected to begin filming this year in Louisiana.
