What Happens Next? - 10 MORE Planned Seasons Of Cancelled TV Shows

10. Constantine

After the success of shows like Arrow, The Flash, and Legends of Tomorrow, the Arrowverse seemed unstoppable. In 2014, the studio decided it was time to introduce one of the most beloved comic book characters, John Constantine.

Despite the fact the lead actor, Matt Ryan, received a lot of praising for breathing life into the iconic demonologist, Constantine became the first show in the Arrowverse to be cancelled, forcing the occult detective character to be repurposed for the show, Legends of Tomorrow.

Matt Ryan reprised the role in the animated series, Constantine: City of Demons but that too was canned after only five episodes. Ryan continued to play the role in animated films but fans were still frustrated there wasn't a proper continuation of the original show.

According to the creators, Daniel Creore and David S. Goyer, Season 2 would have introduced the paranormal superteam, the Justice League Dark. The original line-up for the group was Deadman, Madame Xanadu, Zatanna, Shade, Mindwarp, and Constantine. Some of these characters did appear throughout the Arrowverse but it would have been amazing to see the JLD in live-action for the first time.
