Well, from the same Thanksgiving source, comes the word that the
upcoming DC’s Legends Of Tomorrow TV show is planning to radically
switch casts and missions each season. As a model. it’s being compared
to Justice League Unlimited cartoon.
Which means it is planned for Matt Ryan‘s John Constantine to appear as a series regular in 2017’s season two.
The show is also looking to cast Steven R McQueen, who plays Jeremy
Gilbert in The Vampire Diaries as another new hero during season two as
well.
