Blowfish (2011)

Both films have very little dialogue, still the chemistry between the leads is there and the stories are touching.

Both are mature movies that have nudity and explicit sex scenes. Also both movies are about a man (who is still in love with the woman who left him) meeting a woman (who's boyfriend has cheated on her) and how they fall in love. But My P.S. Partner is a comedy, while Blowfish is a slow paced movie with hardly any talking.
