Frederick Fairley and Louis
The interaction between these two characters in this 1948 version of "The Woman In White" always cracked me up. Frederick would give Louis cues as to what would aggravate him and Louis always complied. I never read the book but I think the part was beefed up for the two actors and John Abbott gave a perfect comic performance as the nerve wracked Frederick Fairley.
