"KICK-ASS" CAST IN PERSON: The "Twilight" people have stopped by there. Then "Glee." And now the top trio of the soon-to-open "Kick-Ass" -- Aaron Johnson, Christopher Mintz-Plasse, and Chloe Moretz -- will be dropping into the Hot Topic at Hollywood & Highland for some fan chat-ups. There are t-shirts to get, wristbands needed, and so we recommend reading everything before heading out. 5 p.m.
IAN MCEWAN: The heavily accoladed author of "Atonement" and the beautiful "On Chesil Beach" and "Saturday" will be at the Japanese American Cultural Center talking "Solar," his new book, and other writerly topics, we imagine. A rare opportunity to see the London-based scribe live. 8 p.m., $25
STRIPPED STORIES: Would you go on the stage of the Upright Citizens Brigade and reveal your most unrevealable secrets, if blue-minded hostesses Giulia Rozzi and Margot Leitman asked you to? You can find out tonight. And you can find out more about the show, which has been making the buzzed-about rounds. 11 p.m.
