Vinegar Hill

(8-10 p.m., CBS3) - You catch more flies with honey than with vinegar. Does the same hold true for nasty marriages? In this 2005 TV movie, Mary-Louise Parker stars as Ellen Grier, a teacher who winds up having to move in with her in-laws. Once there, she finds out Mom- and Pop-in-law don't love each other. How inspiring for her. Tom Skerritt, Roberta Maxwell, Larissa Laskin, Tim Guinee and Betty Buckley also star.

Men in Black

(8-10 p.m., CW57) - Tommy Lee Jones and Will Smith star as elite G-men chasing down illegal aliens - as in aliens from other galaxies, up to no good on planet Earth. A rollicking, offbeat comedy with great effects, this is one Hollywood blockbuster that actually delivers.

Knocked Up

(10 p.m.-12:10 a.m., HBO) - Bad timing equals good comedy in Judd Apatow's observational comedy about a hookup that potentially could upgrade into a high-speed connection. Seth Rogen, who looks like a miniature poodle and barks like a Great Dane, and Katherine Heigl, a double-dip of praline with caramel, costar in the one about the potty-mouthed pothead and the goddess.
