Kristen Stewart vs. Mia Wasikowska, Robert Pattinson Movie Love: Kit Harington 'Brimstone' Replacement

Reports confirm that both Robert Pattinson and Mia Wasikowska were officially replaced in Martin Koolhoven's upcoming Western thriller, "Brimstone." Interestingly enough, R-Patz and the 25-year-old blonde beauty shared an intimate onscreen kiss in 2014's satirical drama, "Maps To The Stars." So, did Wasikowska make a better love interest compared to Pattinson's former "Twilight" sweetheart, Kristen Stewart?

"Game Of Thrones" hottie Kit Harington will now play Pattinson's original role, while Dakota Fanning takes over the lead. Reps have yet to release any details concerning the switch. Read more on the full story here.

Several Twitter fans are disappointed that the 28-year-old British heartthrob was ousted:

@Shebutnayya: "Sad news today But we love #RobertPattinson as a person & the loss of the role in #Brimstone doesn't change anything."

@4RPfans: "BAD NEWS Kit Harrington & Dakota Fanning have replaced #RobertPattinson & Mia Wasikowska in thriller #Brimstone."

Pattinson's former "The Rover" co-star Guy Pearce also tweeted:

@TheGuyPearce: "Yes it's true, Rob's out unfortunately and so's Mia but thankfully we've 2 great replacements in Kit Harrington and Dakota Fanning... xx Guy."

Will FKA Twigs' fiance and Wasikowska ever reunite onscreen again? Their hot-and-steamy "Maps To The Stars" kiss shocked (and impressed) most viewers:

But did Bella Swan and Edward Cullen make a sexier couple? Well, their sexual chemistry was definitely a lot stronger (and perhaps deeper):

Another interesting fact - Stewart stars alongside Jesse Eisenberg in this summer's highly-anticipated stoner flick, "American Ultra" -

Some fans believe they'd also make a cute couple off-screen. But funny that in real life, Eisenberg's allegedly dating Wasikowska! They both worked together in the critically acclaimed 2013 black comedy thriller, "The Double."

Hollywood's such a small world!

Meanwhile, rumors still suggest that 27-year-old Twigs won't allow her "Cosmopolis" beau to invite K-Stew to their upcoming wedding.
