When video games saved the world – on screen

Reason to play: In movies like Pixels, knowledge of video games can help save the world, or part of it.

As Josh Hutcherson is cast in Seth Rogen TV series Future Man as an awkward janitor whose video game prowess makes him some time travelers' number one pick to fend off alien invasion, we look at three films that have us believe video games can help save the world, or part of it.

Hutcherson, who co-starred in The Hunger Games films and has a pair of James Franco films on his slate (The Disaster Artist, The Long Home), is to feature in Hulu TV show pilot Future Man as Josh Futturman, a cleaner at a sexual health centre who's chosen to spearhead a time-travelling, world-saving exercise, despite his obvious failings in other areas.
