What's the name of that movie?

Meg Ryan and Kevin Kline come to mind… Off to check IMDB

French Kiss?

Wow! I saw that movie, but it was a long time ago. Now you have me wanting to see it again. I don’t remember any more details than you listed. I do remember that finding the root was a very emotional moment.

A Walk in the Clouds with Keanu Reeves and Aitana Sanchez-Gijon.

@gailcalled – Ahhh… That’s the other one I was trying to think of, but then I was distracted by something else and lost it.

A Walk In The Clouds is correct. Keanu Reaves, Gioncarlo Giannini, Anthony Quinn. Terrific movie. Complete hogwash about growing grapes.

A Walk in the Clouds is the movie you’re looking for, but I will chime in to agree that French Kiss is great fun, and also very good is the movie that first sprung to my mind: Up at the Villa. The also protagonists met on a train, and although there is no vineyard, there is a spectacular shot of sun-drying tomatoes. This is possibly the only movie I’ve truly enjoyed Sean Penn in. And Anne Bancroft is in it. :)

Thanks all! Especially @gailcalled. Now I’ll have to rent them both.

Now I remember Anthony Quinn, but I can’t imagine the possibility of me forgetting Keanu.
Thanks, @Judi, for asking this question!
