"Fifty Shades of Grey" cast Eloise Mumford has assured that the BDSM-themed film is "tasteful" as she revealed that all the actresses and actors were sworn to secrecy.

"Fifty Shades of Grey" cast Eloise Mumford will play the roommate of Anastasia Steele played by newcomer Dakota Johnson.

She said that the movie adaptation of E.L. James' book of the same title is in good hands under the eye of director Sam Taylor-Johnson and cinematographer Seamus McGarvey.

"I knew right away it would be tasteful and artistic. And the cinematographer is Seamus McGarvey. He did Anna Karenina. It's going to be beautiful," she told E! Online.

"In the end, the story really is a romance and a love story so it's about that more than anything," "Fifty Shades of Grey" cast Eloise Mumford said.

She stopped short of providing some details of the film as "we've all been sworn to secrecy," although she did offer that Jamie Dornan, who plays Christian Grey, and Dakota Johnson are perfect to play the leads.

According to UK's Mirror, fans wanted more bondage and sado-masochism based on the disappointing preview footage at Cinema Con in Los Angeles earlier this year which left a lot of people confused.

"The focus on the footage was said to be on meaningful looks and lighthearted flirting, rather than whips, chains and a flogging chair. The fans weren't happy," the publication added.

Earlier, Dakota Johnson's dad, "Miami Vice" star Don Johnson said that he won't watch her daughter's movie debut although he claimed that he has no problems with the potentially nude and sex scenes.

"It's not something I would go to anyway," he told London's Telegraph. "I probably will not see it just because it's not a movie I would see. I've never seen 'The Vampire Diaries,' I've never seen 'Twilight.' It's in a category of films that I just wouldn't be interested in."
