2&6pm

Comedy

There’s funny, and then there’s Bill Cosby funny. Sure, he’s a great comedic actor--a few successful TV shows are evidence of that. And the Kennedy Center Honor a few years ago made it official that he’s an American treasure. But there’s no forgetting that he’s also a master of stand-up comedy--with stories that are appropriate for the whole family. At his annual show in the L.A. area, Cosby is sure to make you laugh till your spleen hurts--just as he’s done for 40 years.

* Bill Cosby at the Cerritos Center for the Performing Arts, 12700 Center Court Drive, Cerritos. 2 and 6 p.m. $55 to $65. Limited seats available (800) 300-4345.

7&9pm

Pop Music

Scotland’s Battlefield Band, now in its 31st year, is back on a tour that reaches San Juan Capistrano. The group is weathering guitarist-bodhran player Davy Steele’s recent departure for health reasons, but it has added singer-guitarist Karine Polwart. The quartet’s latest album, “Leaving Friday Harbor,� has plenty of traditional tunes alongside originals by Steele, who left after the album was done, singer-keyboardist Alan Reid, fiddler John McCusker and piper Mike Katz. Among its delightful surprises is Katz’s “Jesse ‘The Body’ Ventura Reel,� surely the only bagpipe-led musical tribute to the flamboyant wrestler-turned-Minnesota governor.

* Battlefield Band, San Juan Capistrano Regional Library, 31495 El Camino Real. 7 and 9 p.m. $7. (949) 493-1752.

Movies

Harrison Ford is at his smirking best in a pair of Indiana Jones adventures presented at the New Beverly Cinema. In 1981’s “Raiders of the Lost Ark,� Ford introduced us to the snake-hating archeologist who ventures far and wide, battling Nazis for treasures of the ancient world. Producer George Lucas and director Steven Spielberg rebounded from a less-inspired second entry in the series (“Temple of Doom�) with 1989’s “Indiana Jones and the Last Crusade,� which sends Jones looking for his father (Sean Connery), who has disappeared while looking for the Holy Grail.

* Indiana Jones Double Feature, New Beverly Cinema, 7165 Beverly Blvd., Los Angeles, Sunday through Tuesday, “Raiders of the Lost Ark,� Sunday 2:50 and 7:30 p.m., Monday and Tuesday 7:30 p.m. “Indiana Jones and the Last Crusade,� Sunday 5:05 and 9:45 p.m., Monday and Tuesday 9:45 p.m. $3 to $6.
