Surprisingly hard - forgot some movies that I've seen! And I can't believe I noticed only one Tom Hanks - of course I would have known Forrest Gump too!
The thing is, he won one Oscar for two movies in one year. This makes it look like he won two Oscars in two different years. Tracy and Hanks won Oscars two years in a row.
I understand, and as you can see on my Best Actress films, Janet Gaynor won the inaugural Best Actress award for three films and they're all listed under one ceremony with three answers. Unfortunately with the removal of my 'merge' button I can't format this in a way that gets the actual point across.
Happy you enjoyed the quiz!
