I'd like to have seen a sequel to a vasly underrated Robert Redford flick called "Sneakers," wherein he led a group of geeky tech misfits to capture a secret encryption device....had Dan Aykroyd, Sidney Poitier, was a fun if technically oversimplified flick...would seem like this group of folks could have embarked on another similar kind of "mystery" adventure...

This will drastically date me, but I remember enjoying the old "9 to 5" movie with Lily Tomlin, Dolly Parton, and Jane Fonda. There were rumors of sequels flying around for years, but it (obviously) never happened. Dabney Coleman was at his absolutely detestable best in this movie...

Sure I'll think of some others after I post this....
