Moguls & Movie Stars: A History of Hollywood
8/7c TCM
Pop some popcorn, settle into a comfy chair and get ready to be regaled with "the story of the first great era of American movies from the 1890s to 1970." OK, actually this is just the first chapter in a seven-part documentary series about the influential men and women behind and in front of the camera. Part 1 is "Peepshow Pioneers," and it spans the gestative years of cinema from 1889 to 1907, with a look at the ambitious visionaries who "played with light and shadow on the screen." The early film clips are fascinating, as are the profiles of the men and women who made it happen. Ray Stackhouse

Monday Night Football8:30/7:30c ESPN With all the airtime for the Manning brothers these days, you'd think they're campaigning for Congress. The quarterbacking brothers bid for a third straight prime-time win as Peyton's Colts host division-rival Houston a week after Eli's Giants held off Dallas. Peyton's last action was a Sunday-night win in Washington prior to last week's bye, which was shared by tonight's foe, the high-scoring but defensively-challenged Texans. QB Matt Schaub and Houston are on a four-game road winning streak and immensely boosted their approval rating around the league with a 34-24 opening-day win over Indianapolis, which had won 15 of the previous 16 meetings.

Weeds10/9c ShowtimeNancy plays a little "Nancy Drew" (as Andy dubs her), and develops a lead on someone who can hook her up with illegal passports. But because this certain, mysterious contact operates in "a no-lady zone," she must allow Andy to handle the assignment by himself. Warren (Richard Dreyfuss) gets his hands on a bottle of Andy's "special drink" and, after a couple of swigs, turns a little spacey and begins to realize that Nancy and the gang's European getaway is no family vacation---and she may never be coming back. — Ray StackhouseMario Lopez: Saved by the Baby10:30/9:30c VH1 Mario Lopez has been an actor, a host on Extra and a reality cast member on Dancing with the Stars.
