Continuity mistake: At Agent Estin's office, Bryant is wearing a plaid shirt with bold vertical pastel stripes, and pink stripes at the edges of his collar, but during the drive home in TC's van, the vertical stripes on Bryant's shirt have changed, though it still has the same pattern. Note the blue stripes at the edges of his collar. (00:06:30 - 00:08:40)
Revealing mistake: When TC and Bryant leave Agent Estin's office it cuts to TC's van on the highway, and as we hear Magnum in the voiceover talking about his dad's advice, "to call the monsters out," we can see the shadow of the helicopter filming this footage. (00:08:20)
Continuity mistake: When TC gets off the phone he tells the others that somebody must go to the Sea Palms Hotel, room 401. During their joint mission, Magnum responds to TC on the walkie and tells him he'll call back when he's in the room. Then Magnum enters room 1201, not room 401 as the kidnappers had instructed, right before the kidnappers call room 1201. (00:37:00 - 00:38:30)
