How the West was won

If the recent Denzel Washington remake has you hankering for vigilante justice, check out the original 1960 version of "The Magnificent Seven," with Yul Brynner leading a ragtag team of sympathetic gunslingers. The all-star cast includes Steve McQueen, Charles Bronson and James Coburn.

Lost in space

Conan O'Brien's track record as a producer of quirky comedies — "Andy Barker, P.I.," "The Jack and Triumph Show" — is long on ambition, short on success. Let's hope "People of Earth" can finally give the late-night host and his team the hit they deserve. Former "Daily Show" regular Wyatt Cenac is stone-cold hilarious as a skeptical reporter who is slowly won over by a support group of alien abductees in small-town USA. If the cross between "The X-Files" and "The Office" appeals to you, then beam aboard.

8 p.m., TBS

Open all night

O'Brien's side projects aren't slowing him down on his night shift. The host, who is now delivering the most absurd and creative monologue in late night, will broadcast "Conan" (10 p.m. TBS) from New York all week with guests Tracy Morgan and Louis CK. For a more traditional late-night snack, check out "The Tonight Show With Jimmy Fallon" (10:35 p.m. KARE, Ch. 11), which welcomes former tenant Jay Leno.
