I was shocked because the actor was getting so much praise from critics. For whatever reason he chose to adopt a HEAVY broken australian-ish accent that at times made him difficult to understand. The always thundering IMAX sound system didn't help matters when trying to decipher his speech among the gunfire :).

But I felt that Jodie Foster (who the critics hated) was great as the cold hearted security chief. To each his own I guess. But be advised, the villlain praised by critics BARELY, and I mean barely speaks english!
