It takes an army to create an army, especially when that army is made up of zombies, giant scarecrows, garden gnomes and a whole lot of other crazy creatures. So, when it came to bringing these monsters to life for the film Goosebumps, rather than use a select few, the filmmakers decided to use, well, all of them.

In this Fandango Movieclips exclusive featurette, you'll hear how producers, makeup artists, visual effects artists, the cast, including Jack Black, and director Rob Letterman came together to create this amazing cavalcade of creepy characters from the pages of R.L. Stine's popular Goosebumps book series.

Goosebumps haunts theaters October 16.
