CBS unveils teasers for new fall shows

CBS has unveiled teasers for the newly-announced shows the network is adding to its primetime schedule.

There are previews of the dramas "Stalker" (about detectives investigating stalking cases in Los Angeles), "Scorpion" (an eccentric genius and his high-tech team fighting threats against the U.S.), "Madam Secretary" (starring Tea Leoni as the U.S. Secretary of State), the spinoff "NCIS: New Orleans," and new comedy "The McCarthys" (about a tight-knit, sports-crazed Boston family).

All those shows are set to premiere later this fall (Two other freshmen series, "Battle Creek" and "The Odd Couple," will premiere at later dates). CBS also released a new trailer for its summer sci-fi series "Extant," which stars Halle Berry and will debut July 9.
