On the one hand, she won a Best Supporting Actress Emmy in 2007 for her role in "Grey's Anatomy." And she's shown that she is the reigning queen of the summertime romantic comedy, appearing in such films as Knocked Up, 27 Dresses and this summer's The Ugly Truth. While these movies didn't set any box office records, they did show that she can star in a movie and help it make it's money back and then some. She already has 3 more movies in the works--Hollywood knows a good thing when they see it.
On the other hand, many people think she has a very "diva"-like attitude. Her Emmy acceptance speech turned some people off, and withdrawing her name from the Emmy's last year because of what she called a lack of suitable material in her character's storylines didn't win her any friends, either--especially among people who work on the TV show. (No wonder the scriptwriters gave her character Cancer this past year.)
For myself, all I know is what I see up there on the silver screen. I saw The Ugly Truth while on vacation last week. What can I tell you? She's very attractive, and she's one heck of an actress. Really. You can see her thoughts and emotions play out across her face and in her eyes. The talent is definitely there, and between the TV show and the movies she's shown she's equally adept at comedy or drama. As long as she picks the right material, she can probably be as big a star as she wants to be.
And if it doesn't occur in a film, maybe some of those "Grey's Anatomy" scriptwriters would be only to happy write such a scene for her!
As something of an added bonus, Ms. Heigl gets her bottom smacked on two seperate occasions by Gerard Butler in The Ugly Truth, once in a dress shop and once in her home. Maybe in a future film, she'll graduate from one-whackers to a complete spanking. Maybe. Don't hold your breath, but we can dream, can't we?
