The computer screen and readout in the bunker near the end refer to 'Project Wildfire'. This was the code name used in Andromeda (1971), which deals with a crashed satellite that infects a community with a deadly organism. The zombie virus in La notte dei morti viventi (1968) was blamed on a crashed space probe.
With this movie, all the installments in George A. Romero's original Dead Trilogy have been remade: La notte dei morti viventi (1968) as La notte dei morti viventi (1990); Zombi (1978) as L'alba dei morti viventi (2004), and Il giorno degli zombi (1985) as this movie (it would later be remade again as Day of the Dead: Bloodline (2017)). This makes it perhaps the only trilogy that has been completely remade, though none of the remakes are related to one another.
Although the film's plot shares little with the original, many of the scenes and situations from the original are duplicated, such as debating on whether or not a fellow member should be killed even though there's a chance he won't become a zombie and a zombie firing a gun.
The song playing in the background, about 7 minutes into the movie, is "Stop, I'm Already Dead" by Deadboy & The Elephantmen, which would later become the theme tune of iZombie (2015), a TV show where the lead character is a sentient zombie.
