10 More Sequels That Totally Ruined The Previous Movie's Ending

10. Jack Doesn't Come Back - Speed 2: Cruise Control

The Bus That Couldn't Slow Down - AKA Speed - is widely regarded as an action classic, partly for its unique premise and partly for the sizzling chemistry between Keanu Reeves' daring police officer Jack Traven and Sandra Bullock's wildcat passenger Annie Porter.

Jack and Annie end Jan de Bont's movie in a romantic embrace, having just survived two brushes with death. This set them up perfectly to return as a couple in the sequel, but when that movie rolled around, Officer Traven was nowhere to be seen. 

In The Boat That Couldn't Slow Down - AKA Speed 2: Cruise Control - Annie and Jack have apparently broken up, as she's now dating another cop, this time played by Jason Patric. She clearly has a type. Reeves was asked to return and was even offered $12 million for the job, but he took one look at the script and decided that the movie wasn't for him. 

Without Jack and Annie's relationship, the second Speed movie wasn't nearly as fun, and this twist made the dramatic ending to the first movie seem like a total waste of time.

Turns out Annie was right - relationships based on intense experiences never work.
