50 Shades of Grey Movie Cast: Charlie Hunnam & Dakota Johnson OFFICIAL Christian Grey & Anastasia Steele! 'Disappointed' Fans Respond to EL James' Viral Labor Day Tweets [PHOTOS]

Sorry Ian Somerhalder/Matt Bomer/Henry Cavill fans. Oh, and Alexis Bledel/Emma Watson/Emilia Clarke supporters, don't fret. NONE of these "Fifty Shades of Grey" fan-favorites snagged the highly-coveted roles of Christian Grey and Anastasia Steele in E.L. James' highly-anticipated film adaptation... but the erotic authoress seems VERY excited about her official casting decisions! On Labor Day (Monday, September 2), James announced that "Sons of Anarchy" heartthrob Charlie Hunnam and fashion model/aspiring actress Dakota Johnson will star in the S&M-inspired blockbuster. Finally, introducing the "real life" Christian Grey and Anastasia Steele!

Here's what E.L. James tweeted early Monday:

‏@E_L_James: "Good moaning all. Hold on to your hats..."

Fans could only expect what she had to say next:

@E_L_James: "I am delighted to let you know that the lovely Dakota Johnson has agreed to be our Anastasia in the film adaptation of Fifty Shades of Grey."

And she didn't leave "Fifty Shades" enthusiasts hanging for much longer...

@E_L_James: "So... Christian..."

@E_L_James: "The gorgeous and talented Charlie Hunnam will be Christian Grey in the film adaptation of Fifty Shades of Grey."

Do fans approve?

Following the viral Twitter annoucement, James tweeted:

@E_L_James: "To all the supporters, lovers and haters - thank you so much for the passion that you have for this project. You all rock. All of you. ♡"

For just over a year now, Mstars has continously updated fans on crazy "Fifty Shades" casting rumors. Now, the wait's officially over. Are readers excited, or disappointed? Here's what some tweeters are saying... most aren't happy:

@sianteesdale: "Disappointed with the choice of protagonists for 50 Shades of Grey, but I'll still watch it to see how different it is to the books."

@TommyWee: "Both leads in the 50 Shades of Grey movie are disappointing. It's now 50 Shades of Chey."

@iiNarry3h: "I am 50 Shades of Pissed off right now that Matt Bomer or Ian Somerhalder didn't get Christian Grey."

‏@naomijaade: "Couldn't think of worse main roles for 50 Shades of Grey than the two chosen, what a disaster."

@XimeCM_ISF: "When I heard about the cast of 50 Shades of Grey.... :(."

@eifaxeifa: "The main casts in 50 Shades of Grey is so bleahhh."

Still, SOME fans believe that the handsome Hunnam is perfect for the role of Mr. Grey. And Johnson's sweet-and-innocent vibe totally fits the part of Anastasia Steele.

"Fifty Shades of Grey" hits theaters August 1, 2014!
