Victor Buono
Victor Buono was terrific in his (too small) role of Sam Hollis; Charlotte's father who was menacing her forbidden lover at the beginning of the film.
What I really find hard to believe is Buono's age in the film! If his date of birth here on IMDb is marked correctly (and I suppose it is), it would mean that Buono was only 26 years old when he depicted Charlotte's father Big Sam. 26! That means he was younger than the character he threatened and actually the youngest person in the entire ensemble cast!
Dance with me my dear. The dance of those who will never return...
