Having starred in “Attack of the 50 Ft. Woman,” playing an evil bug from outer space should be no problem for Daryl Hannah. She’s all that and more in the 2006 made-for-TV shocker “Final Days of Planet Earth” (7 p.m. today, Hallmark), produced by the special-effects wizards Robert Halmi Sr. and Robert Halmi Jr.

“Earth” begins, oddly enough, on the Moon. Faced with an equipment malfunction, a team of space prospectors – under the command of William Phillips (Campbell Scott) – makes a hasty retreat to Earth. Halfway home, Phillips finds his crew missing, and then he’s subjected to some grim experiments.

All of the special effects in the world can’t compensate for a bad script that makes little sense. The capable cast is saddled with some ludicrous dialogue. For reasons unknown, Scott’s character speaks in cryptic gibberish. At one climactic moment he appears to calm himself down and baffle his invertebrate foes by reciting the lineup of the 1969 New York Mets. Leave it to Hallmark to tie an alien invasion movie in with October baseball!

¢ Produced on a much lower budget, the 2006 ghost story “Haunted Prison” (8 p.m. today, Sci Fi) stars Stacy Keach as a demented guard and the last survivor of a prison riot with seemingly supernatural origins. Jake Busey plays Marco, the brains behind a gang of bank robbers who take refuge in the spectral slammer. If that isn’t scary enough, a documentary film crew also descends on the joint. Be advised that “Prison” is much more violent and sadistic than most Sci Fi Saturday-night movies. It’s not suitable for children.

¢ A superhero cartoon with the business acumen of “Dilbert,” the new “Adult Swim” offering “Frisky Dingo” (11:30 p.m. Sunday, Cartoon Network) is the dizziest send-up of office life outside “The Office.”

Please don’t ask me what “Frisky Dingo” means, because I haven’t a clue. While many ponder the failure of network sitcoms to reach younger viewers, they should study the clever, silly shenanigans found here. Young audiences haven’t given up on comedies: They’re just watching cartoons.

¢ Half cooking show, half movie showcase, “Southern Fried Flicks with Hazel Smith” (7 p.m. Sunday, CMT) presents the 1997 made-for-TV movie “The Dukes of Hazzard: Reunion!” featuring original cast members John Schneider, Tom Wopat and Catherine Bach. Between hood slides and spinouts, Smith will talk about recipes and welcome guest star Brad Paisley to discuss his recent CMA nominations.
