It's strange that you bring that up, because it brings me back to my note about Janeane Garofalo.
For years, I held a grudge against Holly Hunter (the voice of Mrs. Incredible) for her portrayal of Norma McCorvey (bka "Jane Roe") in a controversial TV-movie called Roe v. Wade. In an Entertainment Tonight interview about a potential boycott, she said something like "Having a baby just isn't an option for some people."
Fast forward to a few years ago: I was in a thrift store and saw some VHS videotapes from someone's personal collection on sale for $1 each. "What the heck," I thought, "If I don't like what's been recorded on them, I can always tape over it." One of the programs recorded was an HBO TV-movie called Things You Can Tell Just By Looking At Her, an anthology of female-centered stories. One of the stories featured Hunter as a single woman living alone but having an affair with a married man (played by the late Gregory Hines). She becomes pregnant, and she expects him to leave his wife for her and raise their child. He balks, and she calmly and coolly sets about getting an abortion. After the deadly deed is done, she walks away from the clinic (being unable to drive, of course) bearing no expression on her face at all. Then, she suddenly dropped to her knees in the middle of the sidewalk and sobbed uncontrollably.
I don't know what Hunter's personal views on abortion are, but after having played the now-repentant McCorvey as a heroine, it took some major guts to play a woman whose post-abortion regrets were immediate and severe.
Thankfully, I had no reservations about watching a movie starring Hunter when it came to her turn in The Incredibles.
I don’t know about Hunter’s politics (I assume she’s a lib), but I’ve always liked her, going back to “Broadcast News” and “Raising Arizona.”
Generally I don’t worry about the external politics of people involved in a movie, especially if they’re just camera or voice talent because I know how little effect they actually have on the content of a movie. Like Holly Hunter is just a really good actress, love her work with the Coen brothers, Broadcast News is on my must watch every election cycle list (along with Power and Network, they remind me not to take it all so seriously) so I don’t really care what her opinions are. Garofalo has excellent comic timing and delivery, so long as she’s not writing her own material (or even when she is on the rare occasion she stays away from politics) I generally find her pleasant.
I’m just not one of those people who needs to see politics everywhere. Which is why I find things like the lib objections to Knocked Up and Incredibles so funny. Of course libs aren’t the only ones who do it, they just tend to be funnier about it.
