Ariel Winter, best known as the smarty-pants Alex on “Modern Family,” guest-stars in the cable kids’ sequel “Fred 2: Night of the Living Fred” (8 p.m., Nickelodeon). Discovered on the Internet, Lucas Cruikshank returns to character as the motor-mouthed teenager Fred. He has a difficult time convincing folks that his next-door neighbor is a vampire. John Cena of WWE fame and Daniella Monet (“Victorious”) also star in this Halloween-themed, movie-length comedy.

• Martin Mull stars in another ghoulish holiday comedy, this one for a more adult audience. “Oliver’s Ghost” (9 p.m., Hallmark) features young actor Nicholas Stargel as Oliver, an 11-year-old with the uncanny ability to see ghosts and carry on extensive conversations with his spectral companions. This comes in handy when his folks relocate to an older part of town and move in with its previous owner, Clive (Mull), who is loath to share the place with either the living or the dead.

One of the more durable performers in television, Mull has had memorable roles on series from “Roseanne” to “Two and a Half Men.” To me, he’ll always be Barth Gimble, the aggressively smarmy talk-show host on “Fernwood 2 Night,” a show about 30 years ahead of its time.

Rhea Perlman (“Cheers”) also stars here as a kindly neighbor who conspires with Oliver to help Clive “move on” and leave his earthly hang-ups behind him.
