EL SEGUNDO, Calif. — Some celebrate Christmas in July. For others, it's Halloween.

The spooky season officially gets underway this weekend as Midsummer Scream comes to the Long Beach Convention Center. It is said to be the world’s largest Halloween and horror convention, offering a variety of entertainment options.

This year, the weekend-long event goes behind the scenes of some iconic names in horror, with panels that explore the creation of Disney's "Haunted Mansion" film and the origins of Lionsgate's "Saw" movies.

Halloween fans eager for the October holiday will learn what's in store through presentations and panels from Universal Studios Hollywood's Halloween Horror Nights, Six Flags Magic Mountain's Fright Fest and more.

"This sixth year for Midsummer Scream is truly the best yet, as we showcase the full range of Halloween and horror — from the big screen to local haunts to the best of horror-themed games of all sort," said David Markland, co-founder and executive director of Midsummer Scream, in a statement. "There is going to be something to do literally every minute from the moment we open our doors at 6 p.m. on Friday, July 28."

The annual event typically hosts more than 40,000 Halloween and horror fans. Single-day passes range from $35 for adult admission to $140 for a three-day VIP "Gold Bat" pass. Children under 10 are free with an accompanying adult.
