Anna Kendrick travels a lot—that's part of being a working actress, after all—and she's kind of got her various trips down to a science. Literally. She needs drugs to do it.

The 'Into the Woods' star hit 'The Late Show' last night to chat about some of her tricks of the trade, including a well-placed Ambien. Kendrick, always amusing and exceedingly plucky, has a good attitude about the whole thing, likening it to time travel with a surprise, though she did admit to host David Letterman that she's occasionally a little shocked by what does she when she's on the prescription drug. It's nothing too crazy—some DVDs in the fridge, a bunch of scrambled eggs on the stove—but Kendrick does have to wonder what fellow travelers think of her when she starts breaking into her carry-on luggage post-pill.
