The Unsinkable Molly Brown (1964)

Molly Brown (Debbie Reynolds) is determined to rise from her country roots and marry a rich man. She finds one in Johnny Brown (Harve Presnell), who's just sold off his lucrative claim on a Colorado silver mine. With the cash hidden in a stove, Molly accidentally burns it. But Johnny soon strikes it rich in gold, making the pair Denver royalty. But money doesn't ensure happiness and, with their union on the rocks, Molly travels to Europe -- before making an eventful return trip on the Titanic.
