These are journals rather than databases. Whenever you have used a database to find articles, the articles that you found always came from a journal. You might not have really noticed the journal layer. In any case, use these as if they were a database to find articles. Do simple keyword searches. If you are interested in specific films, directors or actors, give those searches a try. When you search a film title, try putting the title in quotation marks if the title is comprised of at least two words.
This journal is focused on Latin American cinematography; however, keep in mind that articles in the journal are published in French, Spanish and Portuguese, therefore, you will need to adjust your keyword searches accordingly if you read one or more of these languages (there are some articles published in English). Most of the authors are, geographically, from Latin American countries and include academics, film critics and directors.

An all-purpose journal on topics regarding Latin American Studies, including cinema. Articles from the journal are published only in English.
Latin American Research Review
This is an all-purpose journal similar to the above. It is open-access, so it should be freely available; however, if you happen to notice that the link has changed, please let me know and I'll fix it. Articles from this journal are published in Spanish, Portuguese and English, so you might want to account for this in your keyword searches.
Journal of Latin American Cultural Studies

The journal was formerly called 'Studies in Hispanic Cinemas' so you may see it under that name. The journal is focused on the Spanish language cinemas of Spain, South America, Central America, North America and the Caribbean along with Brazil.
Databases will allow you to search for articles amongst many journals at once. Arts & Humanities Index has the same interface as Web of Science, but all of the science is cut out and the focus is just arts and humanities research.
