Michael Caine says he is finished with films.

The 88-year-old British screen icon revealed in an interview broadcast Friday that the newly released Best Sellers in which he stars with Aubrey Plaza has turned out to be what is my last part really.

Because I havent worked for two years, and I have a spine problem which affects my legs so I cant walk very well, so the two-time Academy Award winner told BBC radio host Simon Mayo .

And I also wrote a book, a couple of books, which were published and were successful, so Im now not an actor, Im a writer, he continued. Which is lovely, because as an actor you have to get up at half-past six in the morning and go to the studio. As a writer, you can start writing without leaving the bed.
