Eva Trammel and Gideon Cross are Sylvia Day's lead characters in her erotic "Crossfire" series. Since Lionsgate has optioned the series for TV, fans have been busy picking up their dream cast. Amanda Seyfried and Megan Fox are among the hottest female celebs being pegged for the Eva role.

Both Amanda Seyfried and Megan Fox have the natural qualities that make Eva Trammel a strong character. Eva is a feisty, sensual, and take-charge woman who is every inch the opposite of "innocent" (at the beginning of the series, at least) Anastasia Steele. What's more, this girl is also a billionaire. Readers find it easy to imagine Ms Trammel with sexy fire in her eyes and a gorgeous but commanding vibe.

Matt Bomer, Henry Cavill, Ian Somerhalder and Joe Manganiello are among the fan favourites to play Gideon Cross. Bomer and Cavill also happen to remain as two of the top contenders for the Christian Grey role.

"Crossfire" has many similarities to E.L. James' "Fifty Shades of Grey." But Day, who has written several novels in the past, assures fans her work is not a mere FSOG rip-off. Many critics are saying Day's prose is a lot better than James' but the latter's work is more successful by far in worldwide sales.

Amanda Seyfried is currently the subject of rave reviews for her portrayal of the late porn star Linda Lovelace in "Lovelace." In the movie's press day, Amanda told reporters she "felt liberated" after having tackled the role and working on the film's nudity requirements.

Megan Fox is no stranger to sexy scenes, too. As a prostitute in Jonah Hex (2010), Megan looks absolutely smokin' and sassy. She's also been often compared to Angelina Jolie. After giving birth in 2012, the actress quickly returned to her bikini bod. As a baby boy's mom, however, she might not be too keen on jumping into a wild and sexy role.

"She’s the perfect face for a scent that’s intensely alluring and a little bit dangerous,” says Avon VP Denise McEvoy in a statement. Megan is the face for "Instinct," Avon's new fragrance.

Between Amanda Seyfried and Megan Fox, there is no better woman for the role of Gideon Cross' Eva Trammel. Fans could only hope for the best until Lionsgate announces the celebs playing the two lead roles in the Crossfire series.
