Adam B. Vary Senior Entertainment Writer Can San Diego Comic-Con catch a break? For two years, the biggest annual fan convention in North America was forced to cancel the five-day gathering due to the COVID-19 pandemic — placing Comic-Con International, the non-profit organization that runs SDCC, under unprecedented financial strain. Last year, SDCC came roaring back with a masked-and-vaccinated convention that was a robust success, with blockbuster Hall H panels for the “Star Trek” TV universe, “House of the Dragon,” “The Walking Dead” and, especially, Marvel Studios. This year’s Comic-Con — which is scheduled to start July 19, less than a month away — is increasingly likely to have none of those panels.
