2. ‘Soldier’ (1998) — Sequels You Probably Didn’t Know About

While not an official sequel, Paul W.S. Anderson’s 'Soldier' exists in the same universe as 'Blade Runner,' and some fans consider it a sequel. Screenwriter David Peoples (who co-wrote the script for 'Blade Runner') refers to 'Soldier' as a "sidequel." And, hey, Gary Busey's in it! Where there's a lesser-known sequel, there will likely be a Busey.
