Warner Bros. TV and DC Comics are bringing all the kids to Comic Con.

On July 26, the duo will present a three-hour mega-screening at the annual San Diego fan-fest, in which the pilots for Fox's Gotham and CW's Flash will be screened for the first time for the public. In addition, new footage from NBC's Constantine and the third season of Arrow will be shown. Cast members and producers from all four shows are set to make appearances.

WBTV has not yet announced its full panel line-up for Comic-Con 2014 but with the event just weeks away, details are expected shortly.

Just last week, the CW set October premiere dates for both Flash and Arrow, meaning fans who catch the former will be seeing it a full three months before its official premiere date. Meanwhile, Batman prequel Gotham, which does not yet have a premiere date but will air Mondays, is considered to be one of the most highly anticipated pilots of the fall season. Constantine, starring Matt Ryan as the title hero, bows Oct. 24.

Comic Con takes place July 24-27 in San Diego.

Here are the trailers for Flash and Gotham:
