Strikingly similar to the Hong Kong movie 'Lost in Time'
My first thought when I saw the trailer was that this was the lastest Hollywood remake of a Hong Kong movie. The film I was thinking of was 'Lost in Time'.
It wasn't just the fact that the storyline was similar (woman loses fiance, is left alone to raise a kid, struggles to rebuild her life with her finace's best friend, who doesn't quite know how to handle the situation) but also the physical similarities betweenthe actors - especially Benicio del Toro and Lau Ching-Wan. see what you think:

del Toro seems like such an unusual choice for this kind of role. But if the film-makers had been inspired by 'Lost in Time' then he becomes a more obvious choice. In fact, I don't think you will find a Hollywood actor who more closely resemebles Lau Ching-Wan, star of 'Lost in Time'!
