Three new December shows kick off tonight with host Robert De Niro. (Paul Rudd holds court next week and Jeff Bridges hosts the Dec. 18 episode.) But first we zero in on De Niro, recognized as one of his generation's finest actors. The two-time Oscar winner (for 1974's The Godfather: Part II and 1980's Raging Bull) who was also nominated four other times will next be seen in Little Fockers, which is slated for release on Dec. 22. Meanwhile, taking the music stage is Diddy-Dirty Money, an electro-hip-hop threesome comprised of Sean "Diddy" Combs, Kalenna Harper and Dawn Richard. The group is poised to drop the CD Last Train to Paris on Dec. 14. — Dean Maurer

This game matches up linebacker Lavonte Davis and a top-notch Nebraska defense, against a stellar aerial attack led by QB Landry Jones throwing to Ryan Broyles. — Dave Roeder

Engineering the Impossible9/8c Science The saying goes, "Rome wasn't built in a day." We suspect the Roman Colosseum also took somewhat longer to build. Let your couch become the time machine that takes you back to the construction of one of the world's earliest stadiums in the debut of the documentary series examining the rise of engineering wonders from the ancient world and what the iconic structures originally looked like. — Michael ChantInvasion of the Christmas Lights 29/8c TLC If you're looking to jazz up your home's Christmas lights display this year, this hour should provide plenty of inspiration.
