Portuguese cinema has a long tradition, reaching back to the birth of the medium in the late 19th century. Portuguese film directors such as Arthur Duarte, Antonio Lopes Ribeiro, Antonio Reis, Pedro Costa, Manoel de Oliveira, Joao Cesar Monteiro, Antonio-Pedro Vasconcelos, Fernando Lopes, Joao Botelho and Leonel Vieira, are among those that gained notability. Noted Portuguese film actors include Joaquim de Almeida, Daniela Ruah, Maria de Medeiros, Diogo Infante, Soraia Chaves, Ribeirinho, Lucia Moniz, and Diogo Morgado.
