Even more interesting, both movies are made from very good books.
Mrs. Palfrey at the Claremont was written by one of my favorite English writers - Elizabeth Taylor. No, not that Elizabeth Taylor. My favorite book of hers is At Mrs. Lippincott's, there's just something about that slow, intimate, personal kind of book I love.
Mrs. Palfrey stars Joan Plowright and Rupert Friend with a cast of entertaining and funny co-stars. It's a lovely, delicate movie about growing old and finding new friends. You might remember Rupert Friend from the new (and not so good) Pride & Prejudice - he's even better in this movie. If you want to see a beautifully crafted and written movie - I'd see this one.
The Namesake is from a book by Jhumpa Lahiri - another lovely book and is directed by Mira Nair - she of Monsoon Wedding, Mississippi Masala and Salaam Bombay among others. In some ways it has the same feel as Mrs. Palfrey - it's a family story, but this one moves around a lot more, beginning in India, moving to New York and then back to India. It also covers a lot more time, so it moves a lot faster.
But I think you'll enjoy them both. I did.
