Tonight, the networks are giving you a chance to catch up on a few of the week's premieres, plus a great marathon you should watch (if you can).
Homeland (Noon, Showtime) - If you have Showtime and didn't get to see the first season of their stunning Emmy-winning drama "Homeland," a marathon starts today at noon. All episodes air, concluding with the Season 1 finale at 11 p.m. Season 2 begins tomorrow night.
Vegas (8pm, CBS) - A repeat of Tuesday night's debut of a new fact-based crime drama starring Dennis Quaid as a 1960s Nevada lawman who clashes with Chicago mobsters running a Las Vegas casino. Not many people saw it Tuesday night and it's worth watching, so check it out. Also stars Michael Chiklis and Jason O'Mara.
Elementary (9pm, CBS) - A repeat of Thursday's pilot about Sherlock Holmes investigating crimes in modern-day New York City, as a consultant to the NYPD. Another good one you should check out if you missed it earlier. Stars Jonny Lee Miller and Lucy Liu.
Lake Placid: The Final Chapter (9pm, Syfy) - A new sheriff has a big problem on her hands when a poacher unleashes the wrath of giant crocodiles in the fourth installment of this campy horror movie franchise.
Law & Order: SVU (9pm, NBC) - A repeat of the 2-hour 14th-season opener (really just two episodes back-to-back), which involves Capt. Cragen being arrested for murdering a prostitute.
Saturday Night Live (11:29, NBC) - Even SNL is a repeat tonight. It's last season's finale episode with Mick Jagger, Arcade Fire, Foo Fighters and Jeff Beck.
