As Marcus and Mike are planting the bugs in Tapia's house, Johnny Tapia is talking to Alexei and at one point he says "I, me, Johnny Tapia will sever your head off". This is almost an exact quote said by famous mob boss John Gotti caught on wire tap.
Marcus mentions Skittles in this film and Bad Boys (1995). First, as a request to the convenience store clerk-mistaking him for a thief-rather than a cop. Secondly, he tells Mike he has been taking Viagra like the candy-after his "nerve damage".
The remote controlled car is seen under the truck as it enters the compound yet in the next scene it is not under the truck. Then we see the view from the remote controlled car and it is still under the truck.
