Fast and Loose is a 1930 American pre-Code romantic comedy film directed by Fred C. Newmeyer and starring Miriam Hopkins, Carole Lombard and Frank Morgan.

The film was written by Doris Anderson, Jack Kirkland and Preston Sturges, based on the 1924 play The Best People by David Gray and Avery Hopwood.

The Lenox family of Long Island, headed by Bronson and Carrie, is wealthy and respectful of tradition, but their children Bertie and Marion are more irreverent.

When Bertie gets involved with a chorus girl, Alice O'Neil, and Marion falls in love with Henry Morgan, an auto mechanic, the family tries to intervene to prevent their children from marrying beneath themselves.

Fast and Loose was also Preston Sturges' second Hollywood assignment, after The Big Pond (and its French-language version La grande mare).
