Joe Friday brings new initials to Saturdays

According to my scientific survey, cop show fans love series with initials in the title. Hence the popularity of “CSI,” “Law & Order: SVU” and “Navy: NCIS.” The folks at ABC are no fools, so PDQ, the old reliable “Dragnet” becomes “L.A. Dragnet” (9 p.m. today, ABC) and returns for its second season tonight.

You have to wonder how well this gritty police drama will work with “The Wonderful World of Disney” as its lead-in. It’s a rough transition from scenes of Lilo and Stitch hula dancing to Elvis music to watching Joe Friday stare at bloody cadavers dumped in a ditch.

  • Clint Eastwood fans must be feeling lucky this weekend. Eastwood directs the final installment of “The Blues” (8 p.m. today, PBS), which celebrates blues and jazz pianists including Duke Ellington, Professor Longhair, Art Tatum and Thelonious Monk.

Eastwood will also be the subject of a two-hour profile on “Biography” (7 p.m. Sunday, A&E). The star will also discuss his career with host James Lipton on “Inside the Actors Studio” (7 p.m. Sunday, Bravo).

Tonight’s other highlights

  • A cherubic Hawaiian girl adopts a creature from another world in the 2002 animated musical “Lilo & Stitch” on “The Wonderful World of Disney” (7 p.m., ABC).
  • America Ferrara stars in the 2002 drama “Real Women Have Curves” (7 p.m., HBO).
  • Jack Black is host of the 29th-season premiere of “Saturday Night Live” (10:30 p.m., NBC), featuring John Mayer.
