At the beginning, Cole and Hanni talk about Dwayne Johnson. Seann William Scott has worked with Johnson in 3 movies: The Rundown (2003), Southland Tales (2006) and Planet 51 (2009).
After Cole falls off the building and lands on the air cushion, he asked the fireman is he can do that again. Riggs said something similar after getting the jumper down by the same means in the first Lethal Weapon movie.
The production code was T13.21304.
