Three to Tango is a 1999 romantic comedy film starring Matthew Perry, Neve Campbell, Dylan McDermott and Oliver Platt.

Oscar Novak (Perry), an aspiring architect and his business partner, Peter Steinberg (Platt), have just landed a career-making opportunity with a Chicago tycoon Charles Newman (McDermott) who has chosen them to compete for the design of a multi-million dollar cultural center. In a ploy for publicity, Newman has pitched Oscar and Peter in a neck-and-neck competition with their archrivals and former colleagues, the hugely successful (and equally ruthless) Decker and Strauss. Though in a comic twist Oscar is mistaken for a gay man when meeting with Charles Newman. Under the mistaken impression that Oscar is homosexual, and therefore a safe companion for his girlfriend Amy (Campbell), he asks Oscar to keep an eye on her for him. Naturally, Oscar falls for Amy virtually on sight, but she thinks he's gay and thus he is forced to maintain the charade of being gay to avoid getting into trouble with Newman, and losing the commission.
