openbrackets has an entry giving statistics on how often translators are characters in films. She cites the Internet Movie Database.

Here are a very few of the entries:

Leonardo da Vinci: 16
Interpreters: 215
Translators: 136
Serial killers named Bob: 1

You do the search by selecting ‘Characters’ in the pull-down search field and entering ‘translator’ in the second search field. It gives 99 men and 37 women. I wouldn’t trust the database to distinguish accurately between translators and interpreters, however.
