The new "Hangover"... Bridesmaids?

I do adore the trailer for the new film "Bridesmaids" which drops this tomorrow. I do hope for the best for Maya Rudolph and Kristen Wiig. Will Rudolph who I think usually gets cast as the "Nice gal nextdoor" type get the chance to shine her comedic chops since leaving SNL some years back, one can only hope. Wiig whom is a writer of this will hopefully carve a place in stone where Lorne Michaels will not place a stranglehold on her present and post SNL run (whenever that days comes to an end)...   Will this mark an end of her SNL run as well if this film is a HUGE hit? Only the box office will tell... as the "Numbers never lie".   But I was really surprised by the comedic side of actress Rose Byrne, whom is mostly know for heavier dramas as I have easily forgotten that she was in "Get Him to The Greek". But she seems to play a character with sex appeal which comes off very well (at least in this trailer). I can only hope. And Melissa McCarthy (From "Gilmore Girls" and "Mike and Molly") is roughing it with a character that seems to wear no make up throughout which has me wondering if there's going to be this 180 degree turn into an attractive woman as it nears the actual wedding (Cliche anyone)... Also I've noticed that "Wilson Phillips" are in this film as well which also has me wondering if there is another cliche where the lead characters sing a "Wilson Phillips" song and then they run into the singers whom will end up singing that song. -OR- will we hear the song throughout and the "WP" sing the particular song somewhere in the film...   And just whom will be the "Zach Galifianakis" of this film.... Hmm, I guess many will find out after this weekend.   But either way i hope for the best as this film must compete with the "Hangover 2" which I believe is pushing it. But like I said earlier "Numbers Never Lie"
