During the credits you can hear that another bomb has been discovered. When Martin and Roger show up in their car, they have this discussion again whether or not to go in. Just as they stop at the building, the whole building explodes and you can hear Martin saying, while backing up the car, "I hope nobody saw us".
The credits thank the city of St. Petersburg, Florida, where the last bomb explosion was filmed and the hotel Soreno destroyed, but they misspell the name of the city as 'St. Petersberg'.
