SAN DIEGO (AP) — "The Strain" is evolving in its third season.
The cast and crew of the FX horror series debuted new opening credits and the first part of the third-season premiere Thursday afternoon at San Diego Comic-Con International.
"This season is really an all-out battle for the soul of New York," said "The Strain" executive producer Carlton Cuse.
The clip featured Corey Stoll's cautious scientist Ephraim Goodweather tinkering with a biological weapon to combat the series' vampire-like creatures and Kevin Durand's street-wise exterminator Vasiliy Fet teaming up with a group of soldiers.
"This knowledge that he's been compiling since a very young age about the underground New York has made him very valuable at this point in time," Durand said. "He starts working with this new group. We won't go too far into that."
Durand was joined at the pop-culture convention by his "Strain" co-stars Ruta Gedmintas, Miguel Gomez, Richard Sammel and co-creator Chuck Hogan. At the beginning of the panel, the group premiered a goofy rap video starring the cast.
Cuse said the show's freaky creations will be evolving and new flashbacks will shed light on the series' monstrous mythology. The third season, which is scheduled to debut Aug. 28, will be 10 instead of 13 episodes. That's by design.
"We wanted to increase the narrative velocity of the show," Cuse said.
