Warning: SPOILERS for The Sandman The way Johanna Constantine's (Jenna Coleman) last name is pronounced in The Sandman may sound strange but there's a reason why it's different from how audiences are used to hearing «Constantine» said.
Executive produced by Neil Gaiman, The Sandman is the long-awaited adaptation of his beloved DC Comics graphic novels. Coleman's Johanna Constantine joins Tom Sturridge, who plays the title role of Dream of the Endless AKA the Sandman, and they are joined by a host of eclectic supernatural beings like The Corinthian (Boyd Holbrook), Death (Kirby Howell-Baptiste), and Lucifer Morningstar (Gwendoline Christie).
Johanna Constantine is a character from The Sandman comics but most audiences will be familiar with John Constantine, who has appeared in his own 2005 film starring Keanu Reeves, his own NBC series, and in DC's Legends of Tomorrow, where Constantine (played by Matt Ryan) became a main character and a member of the Arrowverse's misfit superhero team.
In The Sandman comics, Johanna is John's ancestor who met Dream in the 1700s and helped him with a dangerous mission during the French Revolution.Read more on screenrant.com
