Four stars of a popular streaming series are scheduled to headline Edmonton’s comic expo later this year. Organizers for the Edmonton Comic and Entertainment Expo announced Thursday that The Boys cast members Karl Urban (Billy Butcher), Erin Moriarty (Starlight), Tomer Capone (Frenchie) and Colby Minifie (Ashley Barrett) will grace the 13th annual edition of the pop culture event. Fans attending it at the Edmonton Expo Centre Sept. 18-20 can see and meet them and others during autograph sessions, photo opportunities and live question-and-answer sessions. More celebrity guests will be announced in the coming weeks, with a full schedule expected in early September, the Edmonton Expo said. Tickets are now on sale. The event also features hundreds of vendors and artists. The Boys recently saw record numbers of viewers for its final season on Amazon Prime, with the streaming service reporting it reached 57 million viewers per episode, the highest number for the series that ran for five seasons.
