Inside Man Easter Egg - Pizza Delivery

In the scene where the food is about to be delivered to the bank robbers and hostages, two policemen enter the frame from the left carrying pizza boxes. The shot is angled in such a way that you can briefly see the tops of the boxes -- look carefully (slow motion may be required) at the second policeman's pizza box - the box is clearly labeled "Sal's." Sal is the name of Danny Aiello's character in Spike Lee's first film, "Do the Right Thing," and "Sal's" is the name of his pizzeria!
