RoboCop 3 was shot in Atlanta, using many of the buildings that would soon be torn down to make room for the facilities for the 1996 Summer Olympics.
Similar to its predecessors, the 1994 TV series (and Prime Directives) use Canadian locations as a stand-in for Detroit. The 2014 film itself uses Toronto, Vancouver and Hamilton... though apparently they finally used Detroit itself at least once.
Defictionalization: There is a real life company called Omni Consumer Products. They specialize in... making Defictionalized products. In a nicely full circle manner, the company's owner gave 25,000 dollars to a project seeking to build a statue of RoboCop in Detroit.
Keep Circulating the Tapes: The first animated series. Thanks to MGM and Disney (who owns the library of its studio Marvel Productions) having to share dibs on it, there are no DVD releases planned for Region 1. All that's available of the series are the three VHS releases from 1991, which are difficult to track down. Averted in the UK, where the entire series was released.
The Other Darrin: Not counting the remake, four actors have played live-action Robocop: Peter Weller (RoboCop 1 & 2), Robert John Burke (RoboCop 3), Richard Eden (1994 TV series) and Paige Fletcher (Prime Directives miniseries).
Gary Bullock, who played the doctor who carved up Duffy in RoboCop 2, also appeared in RoboCop 3 as the gas station clerk who deals with Otomo stealing a map and slicing through a sign.
The Series had a few actors who would appear in later installments. Blu Mankuma, wno played Reed's counterpart, Stan Parks, voiced a version of Reed in Alpha Commando. Maurice Dean Wint and Geraint Wyn Davies, who respectively played John Cable and David Kaydick in Prime Directives appeared in The Series as a gang leader in "Officer Down" and an OCP executive in "Provision 22" (again respectively). Lastly, Daniel Kash, who played cartel boss Reggie Braga, played Corrupt Cop John Lake in the reboot.
