While most of trailer is similar to its online one, an additional six seconds were added after the online trailer as an exclusive treat to fans. These six seconds will not be screened anywhere else but were only revealed at the event. Attendees were also given posters of either Batman or Superman that were exclusively available at the IMAX event.
