I think some of what Kirsten said during that interview got a bit 'lost in translation' shall we say.
The 'pain' Kirsten mentions was clearly mental rather than physical. I also seriously doubt she ever considered giving up acting 'for good', more likely she knew she needed a long break.
My take on the situation is that Kirsten went to the Cannes Film Festival last year expecting Marie Antoinette to be well received. As we all know the film got pretty mixed reactions and Kirsten came back from Cannes feeling quite depressed (Tellingly she mentioned in an interview before the films US release that she was amazed how Orlando (Bloom) could just shrug off negative reviews of his films).
Kirsten then went straight into a hectic month of filming some pretty depressing scenes for Spider-Man 3, no doubt this was probably the last thing she felt like doing at the time.
This is no doubt the main reason why she pulled out of appearing in 'Be Kind Rewind' last autumn, and also probably why she was so keen to appear in 'How To Lose Friends'. It's a 'fun movie' as she puts it.
Oh and mark you're quite correct....Never grow up !
