The opening of the attraction was delayed from an original April, 1998 date due to an outbreak of F3 tornadoes in Orlando from an El Nino jet stream. Out of respect for the 43 deaths from the tornadoes, Universal not only delayed the opening until May 4, 1998, but donated a large amount of money to the victims' families.

Following the 9/11 terror attacks on September 11, 2001, the address number of a firehouse facade in the attraction's extended queue had to be altered from "9-1-1" to "2-9-1".

Replaced Ghostbusters Spooktacular (1990) at Universal Studios Florida.
