Collect 'Em All! Our Guide to Celebrities Pressing Flesh in New York This Week

Because cases of mistaken celebrity identity can be really annoying, here follows a list of some stars—most of whom are out-of-towners—in New York over the next seven days. So if you happen to find yourself at, say, Da Silvano on Wednesday night and could swear that Tom Hanks is sitting at the next table over, you’ll know that it’s probably him. (Mr. Hanks comes to town today to promote his new film, Charlie Wilson’s War.)
