'Fifty Shades Of Grey' Casting: Who Should Play Series' Other Hot Young Couple?

Whether Monday's "Fifty Shades of Grey" casting news left you squealing in delight or seeing a shade in keeping with Christian Grey's Red Room of Pain, actors Charlie Hunnam and Dakota Johnson are here to stay as the bad-boy billionaire and his paramour Anastasia Steele (so you can kindly put away your petitions, okay?). And amid all this furor, an important detail has been overlooked: Director Sam Taylor-Johnson has yet to cast the film's other hot young couple, Kate Kavanaugh and Elliot Grey.

Fans of E.L. James' best-selling series will surely recognize these names. Kate is Ana's best friend and roommate—a budding journalist who comes down with the flu the day of her big interview with Christian Grey. She sends Ana in her place, and the rest is, well, you know. Elliot, on the other hand, is Christian's easy-going adoptive brother, who embarks on a relationship with the feisty Kate after meeting her at a bar.

Miss Kavanaugh is described as a strawberry blonde, with green eyes and curves to spare. And if it's a strong-willed stunner producers are looking for, we'd recommend "Pitch Perfect" actress Brittany Snow, who went so far as to hop into the shower with Anna Kendrick to convince her to join the Barden Bellas. But if it's a more striking physical resemblance they're after, how about Elizabeth Olsen, who was a one-time contender for the role of Ana? (She's probably already familiar with the material too!) For a third option, let's tap Amber Heard. She did land Johnny Depp, after all. Elliot Grey would be a piece of cake!

As for 30-something Elliot, whom E.L. describes as tall and muscular with curly blond hair and blue eyes—oh, if only Simon Baker were a decade younger, he'd be perfect! "Nashville" actor Chris Carmack could be a good stand in (sans cowboy hat, of course). We could also see a clean-shaven Travis Fimmel of "Vikings" fame filling the bill for a muscular blond hunk. And, the obvious choice, Armie Hammer. But would he take such a small role?

"Fifty Shades of Grey" is slated for an August 1, 2014 release.
