Monster-Mania Con is bringing a mix of horror icons, cult favorites and “Stranger Things” talent back to South Jersey this spring. The long-running horror and pop culture convention returns to Cherry Hill from March 6-8, taking over the DoubleTree by Hilton for a weekend of celebrity guests, autograph sessions, panels and memorabilia. Among this year’s headliners is Linda Hamilton, who appeared in the final season of “Stranger Things” and is best known for her role as Sarah Connor in the “Terminator” film franchise. Hamilton is scheduled to appear Friday and Saturday and will reunite with her “Terminator 2” co-star Edward Furlong for a joint photo opportunity. Organizers say more guests will be announced ahead of the event.
