Some of the most exciting new film and TV trailers are released at San Diego's Comic Con and this year is no exception. Watch a Kiwi star battle zombies, take a trip behind-the-scenes of Star Wars, and watch the debut of a dark new anti-hero.

1. Star Wars: The Force Awakens - Behind the scenes

Although it doesn't show much new footage outside of last year's first movie trailer, this behind-the-scenes reel adds to the building excitement around Star Wars - Episode 7.

This footage emphasis the focus on physical sets and costumes, and the filmmakers are "keeping one foot in the pre-digital world".

It's a refreshing reassurance for the original fans turned off by the over-reliance on digital special effects in episodes one to three.

Fans are already analysing props seen in background shots for clues on which classic characters might make an appearance.

2. Fear the Walking Dead

Starring New Zealand's own Cliff Curtis as a recently divorced dad, Fear the Walking Dead is a prequel to the massively popular Walking Dead series and shows how the zombie apocalypse started in Los Angeles.

Producer Dave Erickson told Comic-Con audiences that the show "starts as a family drama, and we filter the apocalypse through that", which this trailer makes evident.

3. Heroes Reborn

The originally Heroes series debuted in 2006, but quickly went downhill, following a compelling first season. The trailer for Heroes Reborn, a 13-episode reboot, picks up the story of the 'evolved humans' five years after the previous finale.

It shows dark times for the EVOs, who are mostly dead or hiding, as they are hunted by tactical units. Despite the reservations many viewers had about this reimagining of Heroes, the trailer manages to capture some of the excitement of the first season.

4. The Walking Dead - Season six

The Walking Dead always goes down well with fans at Comic-Con. The trailer for the new season shows Rick getting caught in a struggle with his long-lost friend Morgan, as he tries to change the mindsets of the residents of the Alexandria Safe-Zone. Season six debuts in October, with a 90-minute first-up episode.

5. Deadpool

It's a trailer you won't be seeing in high quality for a few weeks yet, but leaked shaky cellphone footage from Comic Con gives a sneak peek at the new Marvel film Deadpool, which sees Ryan Reynolds reprise the role of the foul-mouthed antihero.

It's gritty and dark and features some NSFW language and a bit of Salt n' Pepa - a rare, R-rated superhero film that's bound to please fans.
