Two films will try to knock The Dark Knight off its #1 spot this weekend, producer Judd Apatow’s stoner action comedy, Pineapple Express and The Sisterhood of the Traveling Pants 2. Pineapple stars Seth Rogen (also co writer) and James Franco, as two potheads who witness a murder and then are forced to go on the run. Judd Apatow has become the king of comedies producing such films as The 40 Year Old Virgin, Forgetting Sarah Marshall and this summers, Step Brothers. Seth Rogen became a comedy all star with the one, two punch of last years hit comedies, Knocked Up and Superbad (both also produced by Mr. Apatow), and should continue his success with Pineapple. Then there’s James Franco, who is getting incredible buzz for his role as a stoner/pot dealer in this movie. In fact, word is that he’s as good as Brad Pitt was in True Romance, the best portrayal of a stoner ever (in my opinion). Opening on a Wednesday, Pineapple will gross $28M over the weekend, with a 5 day take of $42M.

The Sisterhood of the Traveling Pants 2 should enjoy a good first weekend due to its fanbase from the first film and the lack of films playing to the the teenage girl audience. Also opening on Wednesday, Sisterhood should gross $16M over the weekend, with a 5 day take of $26M.

The Dark Knight continues to break records and now sits at #7 on the list of all time domestic blockbusters with an estimated gross of $405M. Expect The Dark Knight to drop a little over 40% this weekend to gross $24M and finally be knocked off the top spot. For the rest of my predictions for this weekend see the chart below.
