Just so we are clear, you are saying that you think Maya Rudolph -- who's two most recent films were Grown Ups and MacGruber, in which she played medium-sized supporting roles in each -- should have turned down the role as the #2 character in this film because it was too low-brow at times.
Ummm, no offense my friend, but lets just say that your budding career as an agent giving career advice to actresses is not getting off to a good start
Bridesmaids has been a huge career boost for the women in it. I like Maya, but she does not exactly have leading lady looks and she doesn't come off as funny most of the time as Tina Fey or Amy Poehler. I think there is an excellent chance that this will be Maya's biggest film and biggest role of her career. In fact, if the horrible were to happen and Maya were to die today, her obit would call her "comedic actress who starred in Bridesmaids and appeared on SNL for a decade." Yes, Bridesmaids would come first, before SNL. Nothing else about her career would be mentioned... unless it was a really long obit.
