In this season of joy, television is delivering major presents this weekend. So what if you've seen many before?

The highlights:

The fresh gift is a new "Saturday Night Live" hosted by Jimmy Fallon. Justin Timberlake is the musical guest at 11:30 p.m. Saturday on NBC. Expect surprise guests and "Duck Dynasty" jokes.

NBC's "Sunday Night Football" should clean up in the ratings. The Chicago Bears take on the Philadelphia Eagles at 8:30 p.m.

CBS will offer more football on "60 Minutes" at 7:30 p.m. Sunday (the delay is because of the NFL). Morley Safer interviews "Quarterback Guru" Steve Clarkson about training children as young as 8 for careers in the NFL. Can you believe that?

ABC will counter with Julie Andrews and one of the greatest opening sequences in movie history. The network will repeat "The Sound of Music" at 7 p.m. Sunday. NBC's recent live telecast with Carrie Underwood as Maria prompted many people to speak of their love for the Andrews version. The 1965 film of the Rodgers and Hammerstein musical cleaned up at the box office, earned the best picture Oscar and made Christopher Plummer a heartthrob for millions. Eleanor Parker, who recently died, is glamorous and crafty as the baroness. But it's Andrews' show for her stellar musical performance. She won the Oscar for "Mary Poppins," but she is more impressive as Maria.

NBC repeats "It's a Wonderful Life" at 8 p.m. Friday (tonight). James Stewart's emotional performance propels this enduring Frank Capra fantasy. Donna Reed, Lionel Barrymore and Henry Travers offer memorable support.

CBS airs colorized versions of two "I Love Lucy" episodes at 8 p.m. Friday (tonight). The hour is called the "I Love Lucy Christmas Special," although the second episode has nothing to do with the holiday and features Lucy's famous grape-stomping. The first episode is a Christmas episode that was not sold in the syndication package that has aired for decades. In that episode, the Ricardos and Mertzes reminisce, and the colorized version gives way to black-and-white flashbacks. The takeaway: Lucy, Ricky and the gang should remain in black and white.

CBS will follow the "I Love Lucy" special with new episodes of "Hawaii Five-0" at 9 and "Blue Bloods" at 10.

This is an especially good time of the year for TCM, which pulls out classic movies. James Stewart is paired with Margaret Sullavan in "The Shop Around the Corner," one of Hollywood's loveliest comedies, at 8 p.m. Sunday.

On Saturday, TCM will offer the unusual double bill of "Jaws" at 5:45 p.m. and "Auntie Mame" at 8 p.m. Rosalind Russell has her best-remembered role as Mame ("His Girl Friday" is her greatest movie, though). Mame tells us, "Life is a banquet, and most poor suckers are starving to death!"

Of course, you have to see life as a banquet to appreciate the bounty.
