TV Remote: What's on this weekend

Aug. 28: Wizards of Waverly Place gets the original movie treatment as the Russo family plans a Caribbean vacation. But Alex (Selena Gomez) doesn't want to go, so she casts a spell to foul up the trip. 8 p.m., Disney Channel.

Aug. 29: In the schlock-fest Mega Shark vs. Giant Octopus, enormous prehistoric sea creatures terrorize the California coast. And you thought pudgy men in Speedos were the scariest things on the beach. 9 p.m., SyFy.

Aug. 30: Want new TV Sunday night? It's all reality except for ABC's astronaut drama Defying Gravity (10 p.m., ABC). CBS has the co-existence shows Big Brother 11 (8 p.m.) and There Goes the Neighborhood (9 p.m.). ABC gives you business "reality" with Shark Tank (9 p.m.). NBC's NFL match-up of the Chicago Bears and Denver Broncos (8 p.m.) might be more "real" than any of those shows. But it's the pre-season, so it doesn't count.
