Looking for the title of a heist movie.

@cinefyl​ hi why did you delete your other message cinefyl, thanks for the help though

@Horst - interesting, I did not delete my other message. I wonder if the system had a glitch. I only posted the one message above about more details...very odd

Hello that is very strange. I got a message you reposted,, but again there is nothing there. A mystery. Hope you got a great weekend ahead nonetheless and thenks for the help!

@cinefyl​ Let's see if you can help me... The movie is American, in English, in color, probably no more than 10 years old. A man, who is a specialist at authenticating things (I don't remember what it was), is called to do a job for a lady. He goes to her house several times but can never see her. He is told that she is a medical condition. Things evolve and he falls in love with her. I don't remember if he ends up seeing her behind a glass wall, or something like that. Nothing direct... Then comes a time when he is going to put money on the "deal", and when he does, she disappears with the money. At the very end, he manages to find her, somewhere exotic, I believe. He could act but decides not to, because of his love for her. That's how I remember the movie. The main actor is NOT Steve Martin, but somehow, it reminds me of him. Thanks
