Olyphant replaces Copley in 'Number Four'

Timothy Olyphant has replaced Sharlto Copley in DreamWorks sci-fi picture I Am Number Four.

According to Variety, Copley was forced to depart the film due to scheduling conflicts with press obligations for The A-Team.

Olyphant will shoot his part in the movie during a break from his FX series Justified.

D.J. Caruso is directing the film, about a group of aliens who escape their worn-torn planet to live on Earth.

Michael Bay is producing the picture, which also stars Teresa Palmer, Alex Pettyfer and Dianna Agron.
