Ten minutes into the movie, the first appearance of the "HitUsUp.com" building has the letters missing on the top. Fourteen minutes into the movie, the letters are there.
(at around 1h 07 mins) Master P states that the car belongs to him. However, after bailing his cousin Mikey (Katt Williams) out of jail, the car appears to be a rental based on the piece of paper attached to the key in the ignition.
When Mickey is typing on his laptop for the first time in the sub shop, a close up of the keyboard shows the letters are inverted.
57 minutes into the movie you can see the shadow of the camera crew reflecting off the wall inside the sub shop.
