Celebrities and others react to latest Sony hack developments

Latest reaction from Hollywood and beyond to the Sony hacking scandal and President Obama's remarks Friday that the studio "made a mistake" in not releasing its embattled film "The Interview":

— "As the events of the past weeks have made painfully clear, we are now living in an age in which the Internet can enable a few remote cyber criminals to hold an entire industry hostage. ... We hope that instead of the "chilling effect" on controversial content, this incident becomes a rallying point for all of us who care about freedom of expression to come together and champion this inalienable right. We stand by our director members Seth Rogen and Evan Goldberg and hope that a way can be found to distribute the film by some means, to demonstrate that our industry is not cowed by extremists of any type." — The Directors Guild of America in a statement.

— "The decision to pull The Interview is historic. It's a case of putting short term interests ahead of the long term. If we don't get the world on board to see that this is a game changer, if this hacking doesn't frighten the Chinese and the Russians, we're in for a very different world, a very different country, community, and a very different culture." — Sean Penn in a statement to MotherJones.com.

— "Ultimately I think the Sony hack will bear valuable fruit. NK through vanity exposed potentially far greater threats we can now prepare for." — Actor Michael Chiklis on Twitter.

— "The level of corporate cowardice here astonishes me...Whether it's the next CITIZEN KANE or the next PLAN 9 FROM OUTER SPACE, it astonishes me that a major Hollywood film could be killed before release by threats from a foreign power and anonymous hackers." — "Game of Thrones" author George R. R. Martin on his blog.

— "omg sony tells these two dimwits to make a comedy about killing a foreign prime minister? wtf were THEY thinking? OMG!" — Roseanne Barr on Twitter.

— "President Obama just said that Sony caving to hackers and pulling #TheInterview was "a mistake."" — Rob Lowe on Twitter.

— "It is not shocking that nobody signed Clooney's petition. Almost nobody here will acknowledge that Bill Cosby has been accused of rape x30" — Filmmaker Judd Apatow on Twitter, regarding George Clooney's failed effort to rally studios and stars behind Sony.

— "We should be in the position right now of going on offense with this. I just talked to Amy (Pascal) an hour ago. She wants to put that movie out. What do I do? ...Stick it online. Do whatever you can to get this movie out. Not because everybody has to see the movie, but because I'm not going to be told we can't see the movie. That's the most important part. We cannot be told we can't see something by Kim Jong-un, of all (expletive) people." — George Clooney in a Thursday interview with industry site Deadline.com.
