10 Movies That Just Got Cancelled

10. Tron 4

The recently released Tron: Ares was obviously intended to revitalise the series' big-screen prospects, complete with an ending which suggests that Jared Leto's Ares will seek out the protagonists of previous film Tron: Legacy - Sam (Garrett Hedlund) and Quorra (Olivia Wilde) - in Tron 4.

But as ever, the sequel's existence was entirely contingent upon the box office success of Ares, and given that the $220 million blockbuster will be lucky to crack $200 million worldwide by the end of run - less than half of what Legacy made 15 years ago - it's instantly killed any plans for Tron 4.

Days after the movie's soft opening weekend, The Hollywood Reporter indicated that Disney would likely now be "retiring" Tron as a cinematic event, instead using the IP's branding for theme park rides, video games, and perhaps TV series.

Sure, it's possible that Disney dusts off Tron a few decades from now for yet another attempt to make fetch happen, but considering that both Legacy and Ares confirmed Tron to be a firmly niche IP that just doesn't have billion-dollar box office appeal, they might also let it rest for good.
