I wanted to establish the common name for American pilot James (S.) Appleby. He has only two credits in the database:

JAMES APPLEBY (1 title, 18 profiles)
- The World According to Garp (confirmed by T!M)

JAMES S. APPLEBY (1 title, 16 profiles)
- The Great Waldo Pepper (confirmed by T!M)

With the larger number of profiles acting as the tiebreaker, James Appleby is the common name. As there's also a British actor named James Appleby in the database ('Fawlty Towers', 'Doctor Who'), this means he needs a birth year as well. I've added that to the forum's pinned "List of Accepted Birth Years with Documentation"-thread right here.
