Isla Fisher

A husband-and-wife team play detective, but not in the traditional sense. Instead, the happy duo helps others solve their existential issues, the kind that keep you up at night, wondering what it all means.

Owen Wilson and Vince Vaughn lead this 2005 comedy as two men who sneak into weddings and hook up with single women - a method they believe they've refined to a formula. However, as they'll soon find out, they never factored love into the equation.
