Are you with Reese Witherspoon or Will Ferrell? “You’re Cordially Invited,” a new comedy directed by Nicholas Stoller, brings together two stars whose movie worlds are nearly as divided as wedding guests on separate sides of the aisle.

The most surprising thing about this by-the-numbers comedy, in fact, is that it comes to us from writer-director Nicholas Stoller. He updated Kermit & Co. so delightfully in “The Muppets,” tartly reconceived the revenge rom-com with “Forgetting Sarah Marshall,” and scored on the small screen with both “Platonic” and the updated “Goosebumps.”
