San Diego Comic-Con is less than a month away and there have been endless rumors that the convention will be packed with exclusive previews and sneak peeks from the hottest upcoming TV shows and movies.

According to Batman-New, fans will get an early preview of "Gotham" on Saturday, July 26. Reportedly participants will get to screen the pilot episode, which will be followed by an appearance of the cast and producers answering questions.

It's also been said that the premiere episode of "The Flash" will also make its debut at Comic Con as well as a sneak peek at "Constantine" and the third season of "Arrow." There will be a lot more superhero exclusives revealed at the event.

It's been rumored that Warner Bros. and DC Comics will debut the trailer for the highly-anticipated "Batman v Superman: Dawn of Justice." Recently, gossip site KDramaStars reported that the trailer had been leaked ahead of Comic Con and it supposedly featured a glimpse of the Batcave and a message from General Zod.

According to reports, Warner Bros. was also going to release a lineup of superhero films for the next couple years. Journalist Nikki Finke leaked the alleged lineup. You can check it out below:

Superheroes aside, Comic Con will also see lots and lots of zombies. According to JoBlo, Warner Bros. Television is going to screen pilot episodes for both "Constantine" and "iZombie."

"Plus, for the first time ever, Warner Bros. Television and DC Entertainment are joining forces for an epic special Saturday night event on July 26, as previously announced, featuring superheroes, Super-Villains, screenings and special appearances, including the world premiere of 'Gotham,'" the site wrote.

"The Walking Dead" has also been generating a lot of buzz and reportedly AMC plans on releasing the Season 5 trailer at the convention. The general public is expected to see the sneak peek footage a few days later.

 Last year at the San Diego Comic Con, AMC released the promo for its fourth season, so hopefully, the network will do the same this year.
