Sefarad on Amazon. Decent 90 minute film telling the amazing story of Captain Basto and the crypto-Jews of Portugal. A story I knew nothing about.
If you have further interest in this and are in Portugal, I recommend going to Belmonte where the last remaining community of the descendants of crypto-Jews still exists. There is a Synagogue, small museum and we had a very interesting tour there with the founder of the museum. Small town but we were travelling with a Rabbi who needed a quiet place for Shabbat anyway so we rented a car and drove here and stayed at the Pousada Convento in Belmonte - with hiking and lovely grounds. Was great stop between the business of Porto and Lisbon (although not geographically between the 2)
