Film fans in New York City have voted director Rob Reiner's 1989 comedy When Harry Met Sally their must-see summer movie.

Those attending screenings as part of the recent Tribeca Film Festival in the Big Apple were asked to name their favourite film for a simultaneous screening in all five city boroughs.

The votes have been counted and When Harry Met Sally came out on top.

As a result, the movie, starring Meg Ryan and Billy Crystal, will be screened for free at outdoor venues in Manhattan, The Bronx, Brooklyn, Queens and Staten Island on Tuesday (24Jun14) as part of the first-ever Film For All Campaign.
