The wonderful Lee Remick made her film debut in the 1957 film A Face in the Crowd. She was just 21 when the movie premiered. To prepare for the role as a baton twirler, Remick spent two weeks on location, living with a teen twirler and her family. She used the time to work on her baton twirling and on perfecting the local accent.
This movie also marked Andy Griffith’s film debut.
You can find A Face in the Crowd on dvd (Amazon link) or watch on Prime Video.
