Wes Craven's 'Scream' reinvented the horror genre with its 1996 release - director Wes Craven had a habit of reinventing the genre, having done so with 1972's 'Last House On The Left' and of course, 1984's 'A Nightmare On Elm Street.'

The 25th anniversary of 'Scream' is approaching, and with Halloween season in full flow, the stars have been recalling their experiences making the horror classic.

Recently, star Drew Barrymore revealed she was originally cast as Sidney, a role that ended up being played by Neve Campbell, and her co-stars, Skeet Ulrich and Matthew Lillard discussed their time on the set.

Speaking to Entertainment Weekly, Ulrich said he failed to grasp that the film was a horror film, and instead approached it like a documentary.

"I saw it as this very serious documentary about two killers in high school and I was researching serial killers and the psychology of them, so I didn't really key into the humour of the story until take one of day one," he admits.

The first scene filmed was the fountain scene, where the main ensemble talk about the recent murder of Drew Barrymore's character and her boyfriend.

Ulrich says he watched Lillard and Kennedy act out their more "humorous moments" in the scene, and he said he was "very confused, thinking they were just doing it wrong."

"I just remember thinking, 'What are they doing?' Don't they know this isn't a serious movie?" he says.

Lillard joked that his co-star Ulrich was "ruining the movie".

"Like, 'This isn't funny. This isn't supposed to be funny, and man, was I wrong," Ulrich says.

Ulrich currently has a role in 'Riverdale' while Matthew Lillard carving out a solid career as the voice of Shaggy in 'Scooby-Doo' projects as well as a role on 'Good Girls' and a brief, memorable appearance in David Lynch's 'Twin Peaks: The Return.'

Upon release in 1996, 'Scream' became a gradual word-of-mouth hit, and spawned a franchise that will receive a new entry next year from the directors of 'Ready Or Not'.
