Warner Bros. Television is bringing a record number of its series –21– down to the San Diego fanboy convention. This comes on the heels of 20th Century Fox TV announcing last week that they’re also showing off a massive 13 shows at Comic-Con. From WBTV’s upcoming lineup there are screenings and panels for its Berlanti Production of Archie Comics adaptation Riverdaleas well as the DC Comics half hour NBC comedy series Powerless starring Vanessa Hudgens. In addition, there’s the upcoming fall TBS half hour comedy series from Conan O’Brien and Greg Daniels, People of Earth about a group of alien abductees.  There’s also the CW TV series adaptation of the New Line movie Frequency about a daughter and deceased father who reunite supernaturally two decades following his untimely death. ABC midseason show Time After Time based on the 1979 novel and movie follows 19th century scholar H.G. Wells who chases Jack the Ripper in a time machine to present-day New York City which is not what it seems. Saturday is huge day for WBTV with a bulk of its block comprised of its DC Comic shows during the afternoon and new fare in the early evening.
