the constructs." The studio also confirmed that the film would have a 3D release. In January 2011, it was reported that Green Lantern had begun re-shoots for key scenes at Warner Bros.

The first footage of the film was shown at the 2010 San Diego Comic-Con. The footage was widely released online in November 2010 with thirty seconds of footage airing the following day on Entertainment Tonight.

This initial trailer was met with a poor reception from fans and, as a result, the film's marketing campaign was delayed. Sue Kroll, the studio's worldwide marketing president stated, "Part of the reason the response to the first trailer was lukewarm was that the big-scale sequences weren't ready to show, and we suffered for it.

A four-minute cut of the WonderCon footage was later released
