Just as Hugh Hefner changes out one blonde girlfriend for another, Hollywood sometimes does the same thing with actors.
When the fancy people in suits who run Hollywood tire of one actor, sometimes they'll swap them for someone new and hope nobody notices. Well I do! Fancy suit wearing man! I noticed!
Megan Fox Vs. Rosie Huntington Whiteley: After Megan Fox called Michael Bay, "Hitler" she was unceremoniously dropped from the 3rd "Transformers" film. Although she claims she left to pursue "other acting opportunities", she was immediately replaced by Victoria's Secret model Rosie Huntington Whiteley. The film plays it off like Shia Labeouf's character broke up with hot Megan Fox and somehow met another hot girl willing to date him. But really, could Labeouf actually get two girls in a row that looked like that?
Ashton Kutcher Vs. Charlie Sheen: After Charlie Sheen was fired from Two and a Half Men for acting like a coked-up lunatic he was replaced by Ashton Kutcher. Sheen said in a statement he's glad he never has "to put on those silly shirts" again. Too bad those silly shirts were the biggest payday of his life and now Ashton Kutcher is going to be laughing all the way to the bank in a bowling shirt. No details yet on what character Ashton will be playing, but Sheen's character is definitely getting killed off. I guess Ashton Kutcher likes replacing roles held by older men (Get it? Like how he took Demi from Bruce Willis? Oh nevermind)
Lindsay Lohan Vs. Malin Ackerman: Lindsay Lohan was supposed to play Linda Lovelace in the film "Inferno" but then she had to go to rehab, was too difficult to insure, and the films director refused to wait around for her any longer. So he got Malin Ackerman to play the part instead. This was supposed to be LiLo's "comeback" role and she's really upset she lost this role. Like, sorry you're a shit show?
Terrence Howard Vs. Don Cheadle: Terrence Howard was replaced by Don Cheadle in "Iron Man 2," when it was suspected that Howard contract was too expensive to renew for the second film. Apparently Howard was the first actor signed to the first Iron Man film and was being paid more than any other actor in the film, so for "Iron Man 2" they offered him between a 50 and 80% pay cut and his agents said "no way."
Bryce Dallas Howard vs. Rachelle Lefevre: Lefevre appeared as the red headed Vampire Victoria in the first two Twilight films and then alluvasudden she was replaced by another red headed actress, Bryce Dallas Howard. Apparently Lefevre was trying to two-time the Twilight franchise and work on another movie at the same time. Although most of us will watch the movies and see two pale red headed chicks and not know the difference, true Twilight fans will know. But really, who cares what twilight fans think, give them a snuggie with Robert Pattinsons face on it and you're good to go.
Lacey Chabert vs. Mila Kunis: One of Mila Kunis's early roles was voicing the character Meg on "Family Guy" but she didn't always have that role. Lacey Chabert (The brunette from 'Mean Girls") originally voiced Meg for all of the first season. Apparently Chabert couldn't or didn't want to commit to more than one season of the show and so they replaced her with Kunis. I bet Chabert is regretting that decision now that Kunis is more famous than toaster strudels ("Mean Girls" reference anyone?) and making pretend sexy time with Justin Timberlake.
