Buffy The Vampire Slayer
The Franchise: Initially a trashy teen horror flick starring Kristy Swanson, Joss Whedon went on to get his hands on the slayer and delivered one of the seminal TV shows of the late '90s, packed with quick wit and sex appeal.

The Franchise: A reboot is apparently on the cards for Marvel's other super-team, after the colourful but uninspired mid-noughties incarnation left audiences cold.

The Franchise: One of DC's stable of thus far unused superheroes, Aquaman is an Atlantean who becomes affiliated with the Justice League. With the latter in the works, surely our fishy friend deserves his own movie?
