Highlights of this year’s Comic-Con include the introduction of the first female “Doctor Who”, played by British actress Jodie Whittaker, and a reunion for the cast of the U.S. television drama “Breaking Bad”.

Celebrations are also being held to mark a decade of the Marvel Cinematic Universe media franchise and the 25th anniversaries of the sci-fi TV show “The X-Files”, stop-motion animated movie “The Nightmare Before Christmas”, and the blockbuster film “Jurassic Park”.

“We love the family feeling here,” said Miguel Capuchino, who was dressed as a male version of a female character from the “The Nightmare Before Christmas”.

“It’s just a bunch of geeks getting together and there’s no judging, everybody’s just very supportive”.

The annual four-day event, started as a get-together for sci-fi fans to trade comic books in 1970, is now the largest comic book convention of its kind, with over 130,000 people attending guest panels and visiting the venues featuring paintings, comics, movies, TV shows and gaming programs.
