However there were many some positive reactions too with @THysteria tweeting: "I lost my ovaries because of the @JamieDornan1's picture from Fifty Shades Of Grey" and @Bomerbabe_Mixer gushing: "@JamieDornan_org Looking good and the look in his eyes *faints*."
@FiftyLover2014 excitedly tweeted: "@FiftyShades looooving the new official still of @JamieDornan1 as Mr Grey!! #amazing #excitedmuch."
And @purple_witch wrote "I . AM . DROOLING. #ChristianGrey looks HOT! jamie-dornan-forever: @JamieDornan1 as Christian."
Sons Of Anarchy star Hunnam made a quick exit and departed from the project just one month after being announced as the leading male.
But it wasn't long before Jamie stepped in with author EL James taking to Twitter to welcome him to "#TeamFifty".
"Stow your twitchy palms ladies... our man is here," she wrote last October. "Welcome to #TeamFifty @JamieDornan1 x."
Jamie stars opposite Dakota Johnson, who is playing his leading lady Anastasia Steele.
While Dakota's innocent looks give her the perfect appearance for the role of the innocent young woman who enters into a submissive relationship with Christian, she previously insisted she isn't worried about the graphic sex scenes in the movie because she "has no shame".
Speaking to US Elle magazine, she said: "I don't have any problem doing anything. The secret is I have no shame."
Fifty Shades Of Grey is the first book in a three part series - it's followed by Fifty Shades Darker and Fifty Shades Freed.
