Feliz día de tu muerte 2

For the scenes inside the university hospital, the sets had to be rebuilt from scratch for this film, as the actual hospital used in the first film had been gutted.

MRI machines do not turn on/off like that. First of all, MRI's are always on, even at night. There is an OFF button, but only for severe emergencies, because once the MRI is turned off - it takes weeks and thousands of dollars to turn it back on. Therefore, as soon as Tree and Gregory enter the room, her screwdriver and his gun would be pulled to the machine. The wheelchair would already be stuck to the machine (there was no reason to put one in an MRI room).

Mid-Credits scene. The five students are picking up trash when Government vehicles arrive to pick them up. They have acquired Ryan's SISSY device and recruit the team for research. First test subject brought into a time loop, Danielle.
