Scientists and other Bay Area survivors of a sudden plague seek refuge on Alcatraz Island in the 2012 shocker “Rise of the Zombies” (8 p.m. Saturday, Syfy). While this grade Z imitation doesn’t pretend to the production values of “The Walking Dead,” it does borrow the notion of a prison as a place of safety.
On the bad side, these zombies seem smart, or motivated, enough to swim and float to the island hideaway. On a positive note, there seems to be a mad scientist working on a zombie “cure.”
‘‘Rise” sports a better and bigger cast than the usual Saturday Syfy fare, including Mariel Hemingway (“Manhattan”), LeVar Burton (“Roots,” ‘‘Star Trek: The Next Generation”), French Stewart (“3rd Rock From the Sun”) and Ethan Suplee (“My Name Is Earl”). For all of the gore, the most monstrous thing about the movie is its dialogue.
