nope. she IS in the film but a very, VERY blink and you miss part she didn't even have a line. She was a person in the crowd. Look for her in the finale, in the wedding bit. She's wearing a red dress and dancing. In the creidts you can totoally tell it's her because she was dancing with AL and FRANK. Pretty coool. but yeah, you can clearly miss it
It was rather pointless in fact.Hope this helps. Look for her on the dvd, much easier..

I didn't see her either, and I was looking. However, I saw her name listed in the credits near the end of the cast list, and her name was shown as "Stacy Keanan". Notice the "y" at the end of her first name? It could be that another actress with the same name and that spelling was in the movie, and IMDb got this one wrong.
