Richard_Pryor,
Finally got to see the movie and just had to make a few comments. White Chicks gets some of it's ideas from the 1959 movie, Some Like it Hot with Tony Curtis, Jack Lemmon, Marilyn Monroe, and Joe E Brown. The Wayans have updated the idea but kept some of the situations the same, such as the Latrell character chasing after Marcus (Marlon Wayans). To compare, the character of Kevin Copeland would be Tony Curtis, Marcus would be Jack Lemmon, and Latrell would be Joe E Brown.
The movie pokes fun of stereotypes, cliche, and is broad comedy not meant to be taken as more than that, comedy.
The scene that I saw in the commercials was with the "White Chicks" in the car attempting (badly) to sing the Vanessa Carlton song, A Thousand Miles, with the other girls. The payoff is later when Marcus is in a car with Latrell and in attempt to repulse him plays the same song only to have Latrell not only know the song but sing it word for word, with emotion, knowing all the words...all the words.
The original idea for the movie came from Shawn Wayans who read an FHM article about Nicky and Paris Hilton and thought a movie playing that type of character would be fun. The movie was called a combination of Some Like it Hot, Big Mama's House, meets, Miss Doubtfire. I have to single out the over the top and then some performance of Terry Crews as the muscular, strong man, who ends up acting more like the blonde cliche. This guy is able to make fun of his character. At a time when a large, muscular, man is generally seen as the intimidating heavy, Mr. Crews throws that idea out the window and becomes the gender ambivilant, but colour conscious professional (whatever)ball player (sorry I'm not into sports).
Will White Chicks save the world, no, it's a broad comedy that I laughed with. The commentary with the brothers was well done and you can tell that the family that laughs together stays together, and makes some money at the same time.
