Is Katie Cassidy Joining The 'Fifty Shades Of Grey' Movie?

Katie Cassidy

Find out who Katie Cassidy is rumored to play in 'Fifty Shades Of Grey!'

The Fifty Shades Of Grey cast is filling up! The latest celeb rumored to be attached to the Fifty Shades Of Grey movie? Katie Cassidy, who may very well be playing Leila.

Cassidy met up with Fifty Shades author E.L. James, who posted the photo below to her own Instagram account with the caption, "Is Katie Cassidy flexible?" (Spoiler alert: Looks like that's a yes!)

Rumors have since spawned that Cassidy will play Leila Williams, a former submissive of Christian Grey (played by Jamie Dornan). Spoiler alert for those unfamiliar with the story: Williams is said to look astonishingly like Ana Steele (played by Dakota Johnson) and was with Grey for two years before he and Steele hooked up.

She eventually left Grey for her husband, then her husband for a lover ... who later dies in a car crash and drives her certifiably crazy. Phew!

Based on Cassidy's resemblance to Johnson's Steele, it seems like she'd be a shoo-in for Leila Williams. Plus, who just hangs out with E.L. James during filming if they're not part of the process?!
