Why a pregnancy? Possible spoiler....

Rating: 10/10 (15 October 2006)

I loved loved loved this movie - what a roller coaster ride. Everybody was fabulous and I thought Mark Wahlberg stole the show. What a cast - it was just one big celebrity after another and everyone should be up for an Oscar. Maybe this will be the one that FINALLY gets Scorsese his Oscar which he so rightly deserves.
Imagine this actress, whom I actually don't ever remember seeing before, finds herself in a movie with all these big names. She's a terrific actress.
But I'm wondering what everyone's thoughts are on why they added a pregnancy there. Usually Scorcese has a point to everything he introduces in his films and I wonder what the point of that was.
Any thoughts?
