Before 2005, the “reboot” was unfamiliar to the film industry. A little film called Batman Begins changed that. Director Christopher Nolan and Warner Bros. took a huge risk in re-imagining the Batman franchise by wiping the entire slate clean: new cast, new director, new story, new vision. And thus, a trend began.

This week, we’ll look at the franchises that have tried to follow in Nolan’s successful footsteps. The definition of a “reboot” can vary depending on the context and whom you ask. Is a reboot always a prequel? Not necessarily. The re-telling of Peter Parker’s origins in The Amazing Spider-Man has made sure of that latest asterisk-led description.
