Well look, I've already found one then
When Harry Met Sally is one of my favourite movies of all time, mostly because I like the fact that they dont fall helplessly in love with each other straight away, but instead it takes 12 years, ex-wives and a steady friendship before they finally realise how they feel for eachother. Plus, the casting was perfect as the two actors were and are very likeable for the charcters of Harry and Sally. Plus, I believe different sexes can be friends without sex, even though their relationship results in it.
